Abstract
A plastic rocker is pivotally mounted in a plastic switch case and operates a conventional movable contact. The rocker has depending sides or legs which resiliently bend inwardly as a result of contacting abutments on the inside walls of the switch case providing a more positive action to hold the rocker and movable contact more securely in the various switch positions.
Claims7
An electric switch comprising a case having an upwardly open cavity defined by spaced integrally formed side walls, fixed contacts in a bottom wall of said case, a movable contact element for selectively bridging said fixed contacts, an operating member having laterally projecting portions received in aligned openings, defined in the facing surfaces of said spaced side walls, said member having a depending central portion, means connecting said movable contact element to said depending central portion of said operating member to provide at least two switch positions, said operating member having a cross sectional shape of inverted U-shape, a web portion of said U-shape integrally formed with said depending central portion of said member, and said shape having integral depending leg portions located in closely spaced relation to said case side walls and having outside surface areas which are located adjacent to and move parallel to areas of said facing surfaces of said case side walls, said adjacent surface areas being of irregular non-planar contour to cause resilient deformation of said depending member leg portions as a result of pivotal movement of said member toward at least one of said at least two switch positions.
