in various forms of telegraphic apparatus, a magnet which receives the circuit current, and is caused by it to bring into into action the power of a local battery for performing the work of making the record; also, a similar device by which the current in one circuit is made to open or close another circuit in which a current is passing
Origin: [Pref. re- + lay, v.]
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, 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".
Chambers 20th Century Dictionary
rē-lā′, n. a supply of horses, &c., to relieve others on a journey: a fresh set of dogs in hunting: a shift of men: a supplementary store of anything: (electr.) an apparatus by which the current of the receiving telegraphic station is strengthened. [O. Fr. relais—relaisser—L. relaxāre, to loosen.]
rē-lā′, v.t. to lay again, as a pavement.
The Standard Electrical Dictionary
A receiving instrument which moves in accordance with impulses of currents received, and in so moving opens and closes a local circuit, which circuit may include as powerful a battery as required or desirable, while the relay may be on the other hand so delicate as to work with a very weak current.
