Low-current, momentary action pushbutton switches, such as PCB-mount ‘tactile’ types, are cheap, and available in an abundance of different styles. Latching types, on the other hand, are often larger, ...

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 ...

The Adafruit Push-button Power Switch is a tidy little design that lets you control a DC power source using an everyday tactile button. The breakout uses a latching analog circuit that is triggered by ...

This is an improved version of Anthony Smith’s designs for a latch on/latch off switch (see the whole series below). The new design switches a 120VAC load, and includes several much-needed details on ...
