Line 4: Line 4:
 +> 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. -- Wikipedia((https://​​wiki/​Relay))
 +Common uses:
 +  * battery isolation when [[electrical:​12v:​alternator|alternator charging]]
 +  * [[electrical:​12v:​lvd|low voltage disconnect (LVD)]]
 +===== latching relays =====
 +Normally it takes power from the trigger source to operate the relay. ​ A latching relay, however, moves from position to position and locks there even when power is removed. ​
