Toggle Switch - Momentary (On-Off-On)

This is a momentary on-off-on toggle switch, meaning that when you pull the switch from the off position to one of the two on positions, it will only stay there as long as you hold it and then spring back. Momentary toggles are often used for winch controls, engine starters and other applications when you don't want the switch to be unintentionally left on, but you can also use it as an input switch for your microcontroller project.
