Most inexpensive pushbutton switches, particularly pc-board-mounting and membrane types, have momentary action. Latching types are often larger and relatively expensive, and they frequently are ...

A latch circuit can ‘hold’ the circuit in either on or off state until any external signal is applied to it. Latch circuit retains its position (either on or off) even after the input signal is ...

This project demonstrates how to build a simple latching power switch using a push button and an LED connected to an Arduino Uno. The LED turns ON when the button is pressed once, and turns OFF when ...
