Abstract

A movable contact piece support structure for a seesaw switch including guide portions formed in walls of the seesaw switch and slits formed by cutting the movable contact piece and bending back a pair of flaps to make a pair of bent portions. The size and shape of the guide portions and the angle at which the bent portions are bent are chosen so that the movable contact piece rests on the guide portions and on a central contact with the bent portions in contact with the guide portions. The guide portions are further shaped such that bent portions slide smoothly on the guide portions as the movable contact piece rocks back and forth between on and off positions of the seesaw switch.
