Knife Switch, Double Pole (Product Code: SLE/PHY/198) is a double-pole, double-throw (DPDT) knife switch used to reverse the direction of a current or to change a circuit over between two paths in physics and electrical practicals. Its brass poles and blades sit on a plastic base and are chosen to ensure good electrical connections on both poles at once. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India.

Key Details

What Is the Double Pole Knife Switch Used For?

With its outer terminals cross-connected, the switch becomes a reversing key: one throw sends current through a solenoid, motor or galvanometer in one direction, and the other throw reverses it. That is exactly what is needed to show a magnetic field changing direction, to run a small DC motor backwards, or to average tangent galvanometer readings taken with the current both ways. Wired without the cross-connection, it moves one supply between two circuits, for example charging a capacitor and then discharging it through a meter.

Check that both blades seat fully in their contacts on each throw, since a half-closed pole gives erratic readings. Keep the brass faces clean and limit use to low-voltage circuits, because the conductors are exposed. It is a practical addition to any set of AC DC circuits experiment kits in a school or college laboratory.

Frequently Asked Questions

What does DPDT mean on the Knife Switch, Double Pole?
On the Knife Switch, Double Pole, DPDT means double pole, double throw: two separate circuit paths are switched together, and each can be connected to either of two positions. One movement can therefore reverse a current or swap between two circuits.

How do I wire the double pole knife switch as a reversing switch?
To use the Knife Switch, Double Pole as a reversing switch, connect the supply to the common (hinge) terminals, the load to one pair of outer terminals, and cross-connect the outer terminals diagonally. Throwing the blades the other way then reverses the current through the load.

What is the Knife Switch, Double Pole made of?
The Knife Switch, Double Pole has brass poles and blades to ensure good electrical connections, mounted on a plastic base. Wipe the contacts clean if they tarnish, and keep the switch for low-voltage laboratory circuits because the brass parts are exposed.

Which experiments need a double pole knife switch?
The Knife Switch, Double Pole is useful whenever a current must be reversed or a supply moved between circuits: reversing a solenoid or motor, taking tangent galvanometer readings in both directions, switching a capacitor between charge and discharge, or comparing two cells.

LED White (Product Code: SLE/PHY/199) is a standard 5mm white light-emitting diode used as a low-power light source in student circuits and LED characteristics experiments in physics and electronics labs. It is packed 100 to a pack, and its listed data — forward voltage values of 3.3 and 3.8, a luminous intensity of 10 mcd and an IF value of 30 — help students plan current-limiting resistors and compare white LEDs with other colours. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India.

Specifications

What Is the White LED Used For?

In an LED characteristics experiment kit, students plot current against voltage for the white LED and see that it only begins to conduct and glow once the forward voltage is reached — a noticeably higher turn-on voltage than a red LED, which opens a discussion of photon energy and colour. The same LEDs serve as the light source for light-dependent resistor circuits, as indicators on circuit boards, and in simple optics and science-fair projects.

Always wire a series resistor with each LED: subtract the forward voltage from the supply voltage and divide by the chosen current, keeping that current below the IF rating. Check polarity before switching on — on standard LEDs the longer lead is normally the anode — because a reversed LED will not light.

What to Specify When Ordering

• The colour: white (this item) or another colour from the standard 5mm range
• The number of packs, remembering each pack holds 100 LEDs
• Battery clips, circuit boards or sensors you want quoted with the LEDs

Supplier

These white LEDs are supplied by Jain Scientific Equipments Private Limited, the company behind the ScienceLab name, to schools, colleges, electronics training centres, dealers and importers. Packs can be combined with circuit boards, battery connectors and other physics items in a single consignment. For vendor records, buyers can note the supplying company’s Importer-Exporter Code AAECJ8618A (DGFT) and GSTIN 06AAECJ8618A1ZT. The ScienceLab company profile has more background.

Related Physics Lab Equipment

These items are often ordered with white LEDs for circuit and sensor work:

• LED Bright Red — compare its forward voltage with the white LED
• LED Blue — another colour for colour and photon-energy comparisons
• Light Dependent Resistor — detects the LED’s light in sensor circuits
• Battery Snap with Crocodile Clip — a quick battery connection for LED circuits
• Worcester Circuit Board — a base for building student circuits

Find more components in Physics Lab Equipment.

Frequently Asked Questions

How many LEDs are in a pack of LED White?
LED White is supplied in packs of 100 standard 5mm white LEDs, enough for a class to build circuits and keep spares for replacements. Order the number of packs you need, and mention any other colours from the same range.

What forward voltage does the white LED need?
The data for LED White lists forward voltage (VF) values of 3.3 V and 3.8 V. White LEDs need a higher forward voltage than red ones, so allow for this when you choose the supply voltage and the series resistor.

Does LED White need a series resistor?
Yes. LED White should always be used with a series resistor that keeps the current below its listed IF value of 30. Work out the resistor by subtracting the forward voltage from the supply voltage and dividing by the chosen current.

Why is no single wavelength given for a white LED?
LED White is specified with colour coordinates of x: 0.31, y: 0.30 rather than one wavelength, because a white LED emits a broad spread of colours. The coordinates describe its white tint, and its luminous intensity is listed as 10 mcd.

Who supplies LED White?
LED White is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, Haryana, India, to schools, colleges, electronics labs, dealers and importers in India and international markets, usually alongside other circuit components and physics lab equipment.

What should a quotation request for white LEDs include?
A quotation request for LED White should give the number of packs, any other LED colours needed, related components such as battery clips or circuit boards, and the delivery location, so everything can be quoted together in one offer.

Lens Holder, Wooden (Product Code: SLE/PHY/200) is a bench-top wooden stand used to hold a lens or mirror upright while students locate images and measure focal lengths in school optics practicals. It takes lenses or mirrors up to 76mm in diameter in the V-shaped slot of a 100mm upright, and an index mark engraved on each end of its 100 x 50mm base shows its position against a scale. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is the Wooden Lens Holder Used For?

The holder is the fixed point of most focal-length experiments. Students stand it beside a metre rule, line up an index mark with the scale, and move a screen or object until a sharp image forms, then read off the distances for a convex lens or a concave mirror. Because it simply rests on the bench, it can be moved in small steps and re-read quickly, which suits the u–v method and the distant-object method alike.

Let the lens settle to the bottom of the V so that its centre stays at the same height as the object and screen, which keeps the image on the principal axis. Clean lenses before use and handle them by the edges. Simple items like this form the backbone of optics lab equipment in India, where many student groups work at the same time.

What to Specify When Ordering

• The number of holders per student group or per laboratory
• The diameter of the lenses and mirrors you use, which must be 76mm or less for this holder
• Any lenses, mirrors or metre rules you want quoted in the same enquiry

OEM Manufacturer

ScienceLab, the trading name of Jain Scientific Equipments Private Limited, is the OEM (original equipment manufacturer) of this wooden lens holder. It is made and finished at the company’s own licensed factory at Saha, Ambala, Haryana, India, and dispatched directly to schools, colleges, dealers and importers without a middleman.

Lens Holder with Base (Product Code: SLE/PHY/201) is a black plastic lens mount on its own base, used to hold a lens firmly upright during light and optics experiments in school and college labs. It houses lenses up to 50mm, a simple locking ring keeps the lens in position, and it comes in a pack of 5 so a group can line up several lenses at once. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is the Lens Holder with Base Used For?

Whenever an experiment needs more than one lens standing at a time, these holders do the job: two convex lenses set up as a simple telescope or compound microscope model, lenses placed in contact to find a combined focal length, or a lens in front of a light source to throw an image on a screen. Paired with a convex concave lens set, school students can set up and change arrangements quickly because the locking ring stops the lens tipping or dropping out when the holder is moved.

Tighten the locking ring by hand only until the lens no longer moves; there is no need to force it against the glass. Wipe lenses with a soft lens cloth before fitting them, and keep each pack of five holders together so a complete set is ready for the next class.

What to Specify When Ordering

• The number of packs, each containing 5 holders
• The diameter of your lenses, which should be 50mm or less for this holder
• Any lenses, light sources or optical benches you want quoted together

Levers Kit (Product Code: SLE/PHY/202) is a class set of graduated plywood beams, fulcrums and matched metal blanks used to investigate the principle of moments and lever balance in school physics practicals. Designed for eight pupils, it contains five 600 x 44 x 3mm beams graduated every 38mm, four 32 x 32 x 64mm fulcrums and forty 25mm square metal blanks whose masses are matched to ±1%. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is the Levers Kit Used For?

Pupils rest a beam on a fulcrum at its centre groove and load metal blanks at the graduation marks on either side until it balances. Because the blanks are matched in mass, each one counts as an equal unit, and because the graduations are evenly spaced, each mark counts as an equal unit of distance. The rule that the turning effect on one side equals the turning effect on the other can then be checked simply by counting — for example, two blanks at four marks balance four blanks at two marks.

Check that the empty beam balances before adding loads, and centre each blank on its graduation line so distances stay true. Keep the plywood beams flat and dry when stored. As mechanics lab equipment in India, the kit gives a whole group a hands-on introduction to moments before they move on to spring balances and standard masses.

What to Specify When Ordering

• The number of kits, based on one kit per eight pupils
• Whether you would like additional blanks or beams held in reserve (ask us)
• Any force meters or mass sets you want quoted for extension work

OEM Manufacturer

Jain Scientific Equipments Private Limited, which trades as ScienceLab, is the OEM (original equipment manufacturer) of the Levers Kit and makes it at its own licensed factory in Saha, Ambala, Haryana, India. Schools, colleges, dealers and importers receive the kit straight from the factory rather than from a trading house.

Working directly with the manufacturer means a request for extra kits, or for a replacement beam or blank, is answered by the team that produces them — just ask us. Read more on the ScienceLab company profile.

See the complete Physics Lab Equipment range.

Frequently Asked Questions

What is included in the Levers Kit?
The Levers Kit contains five plywood beams measuring 600 x 44 x 3mm, four fulcrums of 32 x 32 x 64mm and forty 25mm square metal blanks. Together these parts equip eight pupils to investigate balance and turning effects.

How many pupils can use one Levers Kit?
One Levers Kit is designed for eight pupils. The class shares the five graduated beams and four fulcrums between its groups and divides the forty matched metal blanks among them to load the beams.

Why are the metal blanks in the Levers Kit matched?
The Levers Kit blanks have masses matched to ±1%, so each blank counts as one equal unit of weight. Students can verify the principle of moments by counting blanks and graduations instead of weighing every load.

How are the Levers Kit beams marked?
Each Levers Kit beam is graduated every 38mm along its 600mm length and has a groove across its centre that locates the fulcrum point, so the beam balances in the same place every time and distances can be counted in equal steps.

Who manufactures the Levers Kit?
The Levers Kit is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), the OEM, at its own factory in Saha, Ambala, Haryana, India. It is supplied factory-direct to schools, colleges, dealers and importers in India and international markets.

Can the Levers Kit be supplied for several classes?
Yes. The Levers Kit can be quoted for a single class or as several sets for schools, dealers and importers. State the number of kits, any extra force meters or masses, and the delivery location in your enquiry.

What Is the Solar Bio Fuel Ready-to-go Used For?

It gives student groups a complete, structured course on biofuels. They extract fats from foods and oil seeds, determine fat parameters and convert the fat into biodiesel; they ferment different sugars, split starch catalytically and prove the gases given off; they distil the mash and characterise the ethanol obtained. The final part turns to the fuel cell, where the two multimeters let students record an I-V curve and see how concentration and temperature change the output, before drawing up an energy balance for the whole process.

As a STEM science kit in India’s senior secondary and college labs, it links biology, chemistry and physics in one project. Start fermentations well before the distillation lesson, set up the stand and clamps securely before heating, and keep flames away from ethanol vapour. The Bunsen burner and Supplementary BioFuel listed as extras need to be on hand before the first run.
