understanding latching relays: a comprehensive guide
Release time:2025-06-29 13:13:36
Latching relays, also known as impulse relays or bistable relays, are essential components in electrical circuits, known for their ability to maintain a position after being activated. Unlike regular relays, which require continuous power to remain in their switched state, latching relays only require a brief pulse of energy to change their state and can remain in that state without power. This unique characteristic makes them highly useful in various applications, especially where energy efficiency and space-saving are crucial.
What is a Latching Relay?
A latching relay is a type of electromagnetic relay that uses a mechanical system to lock its contacts into place after a pulse of electricity is applied. The relay typically consists of two stable states—one where the contacts are closed and another where they are open. When an electrical pulse is applied to the relay, it changes the state of the contacts, and it remains in that position until another pulse is received to change it again. This "latching" feature allows the relay to maintain its state without consuming power once it has been switched.
