Abstract:
1. An electrical switch comprising: a housing; a first contact; a second contact supported at a distal end of a first lever, the first lever movably supported by the housing to move the second contact under influence of a switch operator between a first position separated from the first contact and a second position contacting the first contact; wherein the first contact is supported at a distal end of a second lever, the second lever movably supported by the housing to follow the second contact moving from the second position to the first position; wherein proximal ends of the first and second levers are positioned in the housing to provide a shear force between the first and second contact when the first contact follows the second contact from the second position to the first position; wherein the first and second levers are electrically conducting to provide an electrical path from the first and second contacts to corresponding conductors passing through the housing; wherein the first lever is substantially rigid to rotate between the first and second position at a pivot point between the lever and a conductive support; wherein the switch operator communicates with the first lever by means of an over-center spring operating to bias the first lever into engagement with the conductive support at the pivot point.
