When something presses the lever the left (COM) pin and center (NO) become connected internally. When nothing is pressing on the switch, the left (COM) pin and right (NC) are connected. This is a great way to add a switch that connects power to 1 thing or the other depending on whether the lever is pressed or not. Roller ball at the end of the lever so it can rub against surfaces without getting stuck.
