Pushbutton Latch on-off switch circuit for AC devices

Pushbutton latch switch for controlling AC appliances with push on and push off. Hello people, we use the universal on/off switches to switch on and off the AC devices that run on the domestic power supply and even we use toggle switches, as well as momentary switches. But we do not use the Push buttons […]
