Latching Relay: What is it? (Circuit Diagram And How it …

WebMagnetic latching relays are typically single-coil relays designed to be polarity sensitive. When voltage is momentarily applied to the coil with a predetermined polarity, the relay will latch. A permanent magnet is used to hold the contacts in the latch position without the need for continued power to the coil. WebThe latching relay maintains its position after the actuating switch has been released, so it performs a basic memory function. There are two kinds of latching relays: One latching type has two opposing coils with an over-center spring or permanent magnet hold the contacts in position after the coil is de-energized. WebWhat is a latching relay? A latching relay is a two-position electrically-actuated switch. It is controlled by two momentary-acting switches or sensors, one that 'sets' the relay, and the other 'resets' the relay. The … chrome pdf 转图片
