Abstract
An electric snap-action electric switch is disclosed which employs movable contact means having an inverted V-shaped cam surface. The movable contact means is spring biased into engagement along its cam surface with the end of a pivoted operator lever. Upon movement from one extreme position the lever cams and pivots the contact means inwardly of the switch until the end of the lever rides beyond the apex of the V-shaped surface, whereupon the contact means moves with snap action under spring action to change switch circuits. Contact wiping action occurs during inward pivotal movement of said contact means, and abutting stationary contact engagement results from its snap-action movement.
