6mm x 6mm Tactile Mini Push Button (Pack of 2)

These switches are standard input "buttons" on electronic projects. These work best in a PCB but can be used on a solderless breadboard as well. The pins are normally open (disconnected) and when the button is pressed they are momentarily closed.

They come in a pack of 20, they're pretty handy so you'll want to keep them around.

You can find an EAGLE cad package for these in switch-omron:B3F-10XX

Product Dimensions: 6.0mm x 6.0mm x 5.0mm / 0.2" x 0.2" x 0.2"
