Relay Switches

A relay module is a type of electronic component that controls and switches electrical circuits. It is made up of a coil, contacts, and a spring-loaded armature. Controlling high-voltage or high-current circuits using a low-voltage or low-current control signal is frequent.

What is a relay?

A relay is an electronic switch used to cause switching action of different components with an electrical signal as opposed to a mechanical actuation. It is either done purely electrically or electromechanically.


What are the types of relays?

There are many different types of relays - each used in different scenarios or applications

  • Attraction Type Electromagnetic Relays
  • Induction Type Relays
  • Magnetic Latching Relays
  • Solid State Relays
  • Hybrid Relay
  • Thermal Relay
  • Reed Relay

What ways can I use relays in a robotics project?

Relays can be used in places where mechanical switches are generally used. This enables you to implement wireless control over those switches and thereby make the whole project/product more sophisticated. Relays are also used in places where automations are used, mainly acted upon by a trigger.

What is a bad relay?

A bad relay would be a relay that may have been internally damaged. In electromechanical relays, sometimes the mechanical actuator can break or stop working due to build up of dust over time. In a solid state relay, the transistor that operates the relay could get damaged if the voltage supplied to the relay was much greater than what the relay was designed to handle


What is a relay switch? Is it the same as a relay?

Relay switches are just another colloquial term used for relay. As relays are used for switching on/off circuits electrically, it can be sometimes referred to as a relay switch - generally indicating that a mechanical switch was replaced by a relay.

Where can I buy relays online?

Relays can be obtained from almost all online stores including Robocraze. But specific types of relay may vary in availability.

Where can I buy relays at a shop near me?

Relays are available in most electronic stores. However more specific types of relay may be a bit more difficult to find

What is the cost of relays in India?

Relays can vary in cost substantially depending on the manufacturer, rating, extra features like circuit protection, material used, etc.
