Push Button. A Push Button is a type of switch work on a simple mechanism called “Push-to-make”. Initially, it remains in off state or normally open state but when it is pressed, it allows the current ...

555 Timer Delay Off Circuit Diagram. The above circuit uses a 555 timer U1 in mono stable mode. If once push button is pressed, it drives pin2 of timer momentarily to ground that triggers the 555 to ...

The switch circuit consists of two transistors, a comparator, a flip flop and a monostable. As you might expect, the button triggers the flip flops to turn the triac on.

Due to this, U4 TRIAC conducts, passing 230V/110V to J2. When you push PB again, the Q1, Q2 pair opens, stopping current flow through the LED of U3. The TRIACs of U3 and U4 stop conducting, ...

In this programmable LED indicator circuit, it has been used to program a bicolour LED indicator in 10 different modes which can be selected with a single push-button switch. Programmable LED ...
