Questions tagged [latching-relay]
Latching relays are electromechanical devices with mechanical contacts. It has 2 coils, one to latch the contacts closed, the other coil is to latch the contacts open. Only one coil at a time can be driven with a short pulse of current from 10 mS to 100 mS duration. The coil current is not meant to be continuous. The contacts can be SPST or SPDT or DPDT or have many poles for special needs.
