This is a 4 Pin 6mm x 6mm in size with switch height if 5 mm. These switches are standard input “buttons” on electronic projects. These work best in a PCB but can be used on a solderless breadboard as shown in this tutorial. The pins are normally open (disconnected) and when the button is pressed they are momentarily closed. Miniature Single Pole Single Throw switches. Perfect as a tactile reset switch. Rated up to 40mA.
