Patent ID: 8242401

Claim:
An electrical switch comprising: a housing having a support member; a rocker arm pivotally coupled to said support member for pivotal movement about a first axis A and having a first member located on a first side of said axis A, a second member located on a second side of said axis A, and a first substantially planar contact surface on a movable contact coupled to said first member, said rocker arm having a substantially V-shape defining a concave top portion between said first and second members and defining a fulcrum at an apex between said first and second members and being coupled to said support member at said fulcrum; a first substantially planar terminal contact coupled to said housing, said first terminal contact having a planar contact surface for contacting said planar contact surface of said first terminal contact; a lever pivotally coupled to said housing for pivotal movement about a second axis B, said lever being pivoted in a first direction to engage said first member on said rocker arm to move said planar contact surface of said movable contact away from said planar contact surface of said first terminal contact to scrape debris from said planar contact surface of said movable contact and said planar contact surface of said movable contact, planar contact surface of said, said lever being pivoted in a second direction to engage said second member on said rocker arm to move said first movable contact into a sliding engagement with said first terminal contact; and said axis A is substantially parallel to said first substantially planar terminal contact and said first substantially planar contact surface on the movable contact.
