Backlight Capacitive Touch Switch - Various Colors
Add some life to your user interfaces with these backlit capacitive touch buttons from PMD Way.
All the electronics are on the rear of the button PCB so you can position this facing out for a neat finish.
The buttons are simple to use, they have three pins: Vcc, GND and OUT. You can power them with between 2.2~6V DC. When the button is "pressed", the SIG pins goes HIGH up to 3.3V and LOW when no touch detected.
When pressed, the surface of the switch is illuminated via LED. You can use the options menu to select your required color. Free delivery, worldwide.
Switching mode is set to latching "on/off" mode at the factory, however you can set the buttons to momentary (only on when touched) . To do this, solder a 10K ohm SMD resistor across the pads as shown in the yellow circle below:
