Can someone explain to me how a piston switch in a light like an old Inova x5 or a McGizmo works? I'm looking to use one, but I'm a bit shy about the design of it. Thanks guys!
EDIT: I understand the idea and how it turns on and off, but how do you keep it from binding up or becoming crooked in the housing, etc
