Etymology: relais, Fr.
A relay is an electrically operated switch. It consists of a set of input terminals for a single or multiple control signals, and a set of operating contact terminals. The switch may have any number of contacts in multiple contact forms, such as make contacts, break contacts, or combinations thereof. Relays are used where it is necessary to control a circuit by an independent low-power signal, or where several circuits must be controlled by one signal. Relays were first used in long-distance telegraph circuits as signal repeaters: they refresh the signal coming in from one circuit by transmitting it on another circuit. Relays were used extensively in telephone exchanges and early computers to perform logical operations. The traditional form of a relay uses an electromagnet to close or open the contacts, but relays using other operating principles have also been invented, such as in solid-state relays which use semiconductor properties for control without relying on moving parts. 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. Latching relays require only a single pulse of control power to operate the switch persistently. Another pulse applied to a second set of control terminals, or a pulse with opposite polarity, resets the switch, while repeated pulses of the same kind have no effects. Magnetic latching relays are useful in applications when interrupted power should not affect the circuits that the relay is controlling.
to lay again; to lay a second time; as, to relay a pavement
a supply of anything arranged beforehand for affording relief from time to time, or at successive stages; provision for successive relief
a supply of horses placced at stations to be in readiness to relieve others, so that a trveler may proceed without delay
a supply of hunting dogs or horses kept in readiness at certain places to relive the tired dogs or horses, and to continue the pursuit of the game if it comes that way
a number of men who relieve others in carrying on some work
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
Etymology: [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.
A type of device created and designed in various colors, materials, mechanisms, shapes, sizes and styles.
The relay switches are used on the railway tracks.

Kyle Plush parents do it how Kyle Plush parents did it in the old days, write it down on an index card and the card is handed to someone somehow sending the person dispatching on that channel, he said. Plush suffocated after he became trapped under the third-row seat that flipped and pinned him while he was trying to reach his tennis equipment. The teenager told 911 operators where he was located, but authorities were not able to find him. A deputy sent to the scene soon after called in to report that he could n’t find anyone trapped in a van, and questioned if the call had been a prank. 911 DISPATCHER WHO ANSWERED CALL FROM BOY CRUSHED BY MINIVAN SEAT COMPLAINED ABOUT JOB DAYS BEFORE INCIDENT Police said Amber Smith, the 911 operator who answered Plush’s second call, failed to relay information to the additional officers who were at the scene. During the call, Plush explained to Smith the call was not a joke. I am trapped inside my gold Honda Odyssey van in the parking lot of the Seven Hills... Send officers immediately, Plush pleaded. I ’m almost dead.
