A relay is an electrically operated switch. Many relays use an electromagnet to mechanically operate a switch, but other operating principles are also used, such as solid-state relays. Relays are used where it is necessary to control a circuit by a separate low-power signal, or where several circuits must be controlled by one signal.
Impulse relays are a form of latching relay that transfers the contacts with each pulse. Many impulse relays are made up of a. magnetic latch relay and a solid state steering circuit that, upon application of power, determines which position the relay is. in and energizes the opposite coil. The contacts transfer and hold that position when power is removed.
