Product Code : SCL-EI-10722
The Plug-in relay switch is an electricity and electronics teaching component used for demonstrating how a low-power control signal can switch another circuit. It is suitable for school physics labs, electronics trainers, STEM kits and teacher-led activities where students study relay operation, circuit control and switching principles.
Product Description
The Plug-in Relay Switch is designed for modular circuit boards, plug-in experiment panels and basic electronics training systems. A relay is an electrically operated switch; when its coil is energized, the contact position changes and the connected circuit can be opened, closed or changed over, depending on the relay type.
This component helps students observe electrical isolation, control circuits and load switching in a safe, structured format. Teachers can use it to explain normally open contacts, normally closed contacts, electromagnetism, switching logic and automation basics.

Key Features
- Relay switching demonstration: Shows how an electrical signal operates a switch contact.
- Plug-in format: Suitable for compatible circuit boards, trainers and modular experiment panels.
- Electromagnetism concept: Helps explain how a relay coil can move switch contacts.
- Control-circuit learning: Demonstrates low-power control of a separate circuit.
- No volumetric capacity: Capacity is not applicable because this is an electrical teaching component.
- Classroom utility: Useful for physics, electronics, STEM and basic automation lessons.
- Supervised operation: Intended for low-voltage educational experiments under teacher guidance.

How to Use the Plug-in Relay Switch
- Insert the relay switch element into the compatible plug-in circuit board or experiment panel.
- Connect the relay coil to the correct low-voltage supply as per the confirmed rating.
- Connect the load circuit to the correct relay contacts.
- Close the control circuit to energize the relay coil.
- Observe whether the contact opens, closes or changes over.
- Reverse or modify the circuit only after switching off the supply.
Safety note: Use only within the confirmed coil voltage and contact rating. Do not connect mains voltage unless the product is specifically rated, insulated and approved for that use.
Care & Maintenance
- Store the relay element in a dry cabinet after use.
- Keep terminals clean and free from corrosion.
- Do not exceed the contact rating or coil voltage.
- Inspect the plug-in base, housing and contacts before classroom demonstrations.

Frequently Asked Questions
What is a plug-in relay switch used for?
A plug-in relay switch is used to demonstrate how an electrical control signal can open, close or change over another circuit in electronics and physics labs.
Does a Plug-in Relay Switch have any capacity?
No. Capacity is not applicable because this is an electrical switching component, not a volumetric laboratory product.
What does a relay teach students?
A relay teaches students about electromagnetism, circuit control, switching contacts, isolation and basic automation logic.
Can it be used with mains voltage?
Do not use it with mains voltage unless the confirmed product rating and safety certification specifically allow that use. For school labs, low-voltage demonstrations are preferred.
What relay rating should be checked before use?
Check the coil voltage, contact rating, contact type and compatible plug-in system before connecting the relay in any experiment.
Is it suitable for STEM kits?
Yes. It is suitable for STEM kits, electronics trainers and basic automation activities when used with compatible low-voltage circuits.
