  • Patent number: 5568860
    Abstract: An electrical switch with pivot point wiping contact assemblies for scrubbing debris from electrical contact mating surfaces. For each electrical contact within the switch there is a battery rivet having a convex mating surface and a contact rivet which also has a convex mating surface. The contact rivet is mounted onto one end of a resilient wiping arm consisting of conductive material. The other end of the wiping arm is pivotally mounted within the slot of a pocket contact consisting of conductive material. Also connected to the wiping arm is a contact driver which abuts a manually moveable pin. Therefore, by moving the pin the resilient wiping arm rubs the contact rivet mating surface onto the battery rivet mating surface while making an electrical connection.
