STEMMA Wired Tactile Push-Button Pack - 5 Color Pack Shipping:2-4 Weeks This is just the bodyLittle clicky switches are standard input "buttons" on electronic projects. These are just like our Colorful Round Tactile Button Switch Assortment , but already assembled onto a PCB they even have a pull up resistor installed! The pins are normally open (disconnected) and when the button is pressed they are momentarily closed. Each button comes with a candy colored round cap snapped on. You get one of each color blue, white, yellow, red, and black.
