Simple Circuit Module Reed Relay Manufacturer,Supplier and Exporter in India

Simple Circuit Module Reed Relay (Product Code: SLE/EM/30) lets one circuit switch another. A current through the relay coil produces magnetism that makes the reed switch a second, separate circuit, and a series resistor protects the reed contacts from short-circuit damage. Teachers use it to show electromagnetic switching in action and to build simple control circuits, making it a practical part of any electromagnetic kit for schools and colleges. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India.

Key Details

Typical Use

A typical layout uses two circuits. In the first, a cell and a push switch drive the relay coil; in the second, the reed contacts sit in a loop containing a buzzer or LED board with its own supply. Pressing the switch energises the coil, the reed switches and the buzzer or LED responds — showing how a small control current can operate a separate load, the same idea used in door alarms and automatic lighting. Bringing a bar magnet close to the relay also operates the reed, a neat way to link the lesson back to magnetism.

Keep both circuits on low-voltage supplies and wire the control side and the switched side clearly apart so students can trace each loop. Thanks to the protective series resistor, an accidental short on the switched side is less likely to damage the reed contacts, which suits hands-on student work. The coil’s operating voltage is not stated in our listing, so check it with us before choosing a supply.

Frequently Asked Questions

How does the reed relay work?
Current in the coil produces magnetism, which operates the reed and switches a second, independent circuit.

What protects the contacts?
A series resistor protects the reed contacts from short-circuit damage.

What coil voltage and contact rating does it have?
These values are not given in our current listing; contact us for them before planning your circuits.

Can it switch mains-powered equipment?
No. It is a teaching module for low-voltage circuits and should not be connected to mains supplies.

Which modules does it work with?
It belongs to the same Simple Circuit Modules series as the buzzer, lamp holder and LED boards, so these make natural partners on the control and switched sides.

What details are needed for an institutional or tender quotation?
Send the module list, quantities and delivery location; our GSTIN and LEI above can be used for vendor registration.

Do you export these modules?
Yes, we supply schools and distributors in India and international markets.
