Bistable touch button - module with AT42QT1012

Bistable touch button

Description

Turn the mechanical switch into a touch. The switch has dimensions only 22 mm x 23 mm.

The touch button has a built-in capacitive sensor AT42QT1012. It is easy to replace it with the existing mechanical switch. When a touch is detected, the output changes to the opposite state. The switch can work in the voltage range, up to +5.5 V. The switch also has a TIME pin, which can be used to apply additional functions of the AT42QT1012 integrated circuit.

The button has a double-sided tape on the touch-pad side, making it easier to assemble. On request, a module with the 3528 LED diode is available in reverse, i.e. so that it indicates the state of the switch, from the side of the touch field.
