STEMMA Wired Tactile Push-Button Pack

Adafruit STEMMA Wired Tactile Push-Button Pack is a colorful round tactile button switch assembled onto a PCB. Each switch comes with a candy-colored round cap snapped on and has a pull-up resistor installed. The Adafruit pack comes with one of each color of caps (blue, white, yellow, red, and black). The pins are normally open (disconnected), and when the button is pressed, the pins are momentarily closed. Each push-button board has a JST-PH 2mm connector and a matching JST PH 3-Pin to male header cable (200mm) to make wiring easy. The user plugs the cable in and then uses the black wire to connect to a microcontroller/microcomputer ground. The white wire is connected to the input signal pin. The red wire can be connected to the power pin (3V or 5V) if the user wants to activate the pull-up resistor.
