1489-ADA Tactile Switch Buttons (6mm slim) x 20 pack
1489-ADA Tactile Switch Buttons (6mm slim) x 20 pack
US$8.67
These are half the width of classic 6mm tactile switches so they line up better on a breadboard, just plug them into every-other row. These work best in a PCB but can be used on a solderless breadboard. The two pins are normally open (disconnected) and when the button is pressed they are momentarily closed.
