Relay sockets are devices that accept relays, electromechanical switches in which the variation of current in one electric circuit controls the flow of electricity in another circuit

Motor starters and contactors are motor-starting devices.

Electrical connectors are devices that join electrical circuits together.

Thermostats and thermal switches are electro-mechanical on/off switches that are activated by temperature changes.

Solid state relays (SSR) or semiconductor relays are semiconductor devices that can be used in place of mechanical relays to switch electricity to a load in many applications

High voltage relays are used to transfer power for high voltage and high frequency applications.

Electromechanical relays are devices that complete or interrupt a circuit by physically moving electrical contacts into contact with each other
