12x12x21mm Tactile 4 Pin Push Button Switch is widely used as a standard input “buttons” on electronic projects. These work best when you mount it on PCB but can also be used on a solderless breadboard for temporary connections in prototypes. The pins are normally open (disconnected) and when the button is pressed they are momentarily closed and complete the circuit.

This tactile switch also offers reliable dome contact technology and strong tactile feedback, with multiple operating forces to choose from. Applications include telecommunications, consumer electronics, audio/visual, medical devices, testing/instrumentation, and computer/peripherals.

They come in a pack of 3, as they’re pretty handy so you’ll want to keep them around.
