Bistable switches, also known as latching relays, are a unique type of switch that maintain their state even when the power supply is disconnected. They have two stable states, typically "on" and "off," and remain in the last set state until a signal triggers a change. This characteristic differentiates bistable switches from standard relays, which revert to their default state upon power loss.
