SSR Latching Switch Circuit Design With Push Buttons. Posted: June 20, 2025 | Last updated: June 20, 2025. Hi, I'm Bill. I'm a software developer with a passion for making and electronics.

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.

After I proposed: PIC reset and I/O on the same push-button? K Wittingham responded: "Why not use a D-Flip Flop Switch connected to clock and via an RC to the Data input. Release switch quickly data ...

In this case, [Tod] wanted to use a momentary tactile switch to turn something on and off. Instead of going with a microcontroller he built the circuit around a 555 timer .
