Push Button 12mm Red NO

The Push Button 12mm Red NO is a 12 mm momentary push button with a red cap and a normally open (NO) contact. The circuit stays open until you press the button and closes only while it is held down, which makes it a simple choice for start, reset and doorbell buttons, control panels and microcontroller inputs.
