Most modern power-supply control ICs offer built-in overcurrent or short-circuit protection. While some overcurrent-protection schemes are latching, others are nonlatching. When the overcurrent trip ...

The thyristor or silicon-controlled rectifier (SCR) provides a convenient latching mechanism for switching power to a load. However, once the thyristor is triggered into conduction, it supplies no ...

Latching relays latch mechanically or magnetically so you don’t have to maintain current running through the coil to keep them on. Latching relays latch mechanically or magnetically so you don’t have ...

This circuit allows an SPST momentary pushbutton to act as a push-on push-off switch, using a DPDT latching (bi-stable) relay. It was originally intended to allow a single pushbutton switch on the ...
