Switches and Relays

Switches & Relays are used when it's necessary to control a circuit by a low-power signal or where several circuits must be controlled by one signal. Electromechanical protective relays are used to detect overload and other faults on electrical lines by opening and closing circuit breakers. There are many applications which would use a switch or a relay but applications such as Industrial, Industrial control, Automotive and Transport use this technology widely.
