Electrical battery disconnect switches are electromagnetic relays that remotely disconnect a battery from a vehicle's electrical system to prevent battery drain and safeguard against potentially dangerous thermal events. They can also used as power relays for devices with high current consumption.
Activated by the ignition or a switch in the cabin, electrical disconnect switches remotely disconnect the battery from a vehicle's electrical system. Typically, electrical battery disconnect switches are latching relays (also known as bi-stable relays), which latch in the ON or OFF state, consuming no power until it receives electrical stimuli to change states.
