1. In a switch construction comprising a base, at least two stationary contacts mounted on said base, a pivotally movable contact arm, at least one contact area defined by said arm for movement into and out of engagement with said stationary contacts, a spring defining ends engaging said arm on opposite sides of the pivot axis of the arm and having a main body portion spanning said arm, a star wheel having a first point engaging said body portion, a rocker defining a bearing area for engaging a second point of said star wheel, said second point being disposed opposite said first point, said points of said star wheel being located on opposite sides of a line extending through said pivot axis, said bearing area of said rocker being located relative to said base so that the star wheel normally depresses said spring body portion in the direction of said base, a pair of interior walls defined by said rocker on opposite sides of said star wheel, additional star wheel points located for engagement with said walls, said walls being spaced so that only one of said additional points can engage a wall at any time, pivoting movement of said rocker being adapted to cause said star wheel to initially depress said spring further in the direction of said base to thereby increase the pressure of said contact area on a stationary contact, and continued pivoting movement shifting said first and second points of said star wheel to the opposite sides of said line to thereby rapidly pivot said contact arm thereby breaking engagement between said contact area and said stationary contact.
