ABSTRACT:
A switch housing is made with a laminated cover that comprises an inner plate, an outer plate and a metallic sheet that is disposed therebetween. The metallic sheet is formed with a raised portion that defines a raised surface that is a deformable membrane. The protrusion formed in the metallic sheet is disposed through an opening in an outer plate. An inner plate has an opening which is aligned with the opening of the outer plate and the three laminae are spot welded together to define a cover. The laminated cover is welded to a housing with a switching mechanism disposed therein. The deformable membrane of the protrusion formed in the sheet can be attached to a pin that has an outer portion and an inner portion. The outer portion is attached to an external lever and the inner portion is attached to an internal lever. The internal lever is disposed in operative association with a switching mechanism to change the connection status of the switching mechanism in response to movement of the outer lever. The laminated cover eliminates the need for brazing a cup-shaped lever to a cover plate in the region of the deformable membrane.
