this is a less common type of switch. there is basically no power or connection in the switch unless the button on the switch is pushed in. this will be when your lever is closed - so when you aren't pulling the lever, the connection in the switch is bridged and power is being distributed. when you actually pull the lever, the button on the switch is no longer being pushed in and then the connection is no longer bridged and no power is flowing.
some mopeds have wiring that need this type of switch, so if you need it, we got it!
