Bi-Stable Latching Relays

BI-Stable Latching Relays
Bi-stable latching relays serve as battery isolators and battery disconnects in commercial vehicles. In other words, they are on–off switches. Because they require no external power when in the on position or off position, the relays ensure efficiency and produce minimal heat.

What are bi-stable latching relays?

Latching relays (also known as bi-stable relays) are electrically actuated remote switches that are stable in the ON or OFF position. They require power only during the commuting phase, which reduces overall power consumption and waste heat. Latching relays are commonly used for remote battery disconnection and time-delayed battery disconnect applications.

How do bi-stable latching relays work?

In a bi-stable relay, the contacts remain in their present switch position when the excitation current is switched off. Bi-stable relays may use a locking mechanism to mechanically latch the contacts in position or they may use magnetic latching.
