A relay is
an electrically operated switch. Many relays use
an electromagnet to operate a switching mechanism
mechanically, but other operating principles are also used. Relays
are used where it is necessary to control a circuit by a low-power
signal (with complete electrical isolation between control and
controlled circuits), or where several circuits must be controlled
by one signal. The first relays were used in long distance
telegraph circuits, repeating the signal coming in from one circuit
and re-transmitting it to another. Relays were used extensively in
telephone exchanges and early computers to perform logical
operations.
A type of relay that can handle the high power required to directly
control an electric motor or other loads is called
a contactor. Solid-state relays control power
circuits with no moving parts, instead using a semiconductor
device to perform switching. Relays with calibrated operating
characteristics and sometimes multiple operating coils are used to
protect electrical circuits from overload or faults; in modern
electric power systems these functions are performed by digital
instruments still called "protective relays".
