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 ...
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 ...
