Abstract: A slide switch has a pair of opposed, fixed terminals provided on a wafer, and a movable slider contact having two pairs of bifurcated movable contact portions at both ends for slidably contacting the fixed terminals to open or close the switch. Precious metal plating is provided on one pair of the bifurcated movable contact portions at one end of the movable slider contact but not on the other pair of bifurcated movable contact portions at the other end of the movable slider contact.

Abstract: First and second cover plates are snapped together in parallelism to sealingly define therebetween a switch chamber. First and second sets of contacts are fixed to the first and second cover plates inside the switch chamber and a rotor disc formed with electrically conductive patterns on both sides is rotatably supported inside the switch chamber so that the first and second sets of contacts engage with the patterns on the opposite sides of the rotor disc respectively. The switch contacts are retained by interlocking projections of the first and second cover plates which also serve to prevent transverse relative movement between the cover plates.
