Fixed Voltage Regulators ICs with accurate Datasheets

Hello Engineers, we need to get desired or fixed voltage supply many times in many applications while designing some applications or circuits. For this, we need to use voltage regulators. So in this post, I am going to tell you in detail about the basic types of fixed voltage regulators and their classifications on the […]

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 […]
