ABSTRACT:
A rotatable cam operated switch having a cam whose peripheral surface constitutes a cam surface. A guide groove is formed along the entire periphery of the cam surface. A first contact plate closer to the cam and a second contact plate farther from the cam are provided on the peripheral side of the cam. The first contact plate has a first part which extends towards the cam which has a flat surface which is formed such that the dimension thereof in the direction parallel to the axis of the cam is made small, while the dimension thereof perpendicular to the axis is larger, to increase rigidity and preclude bending of the plate towards the cam, thereby resulting in more stable electric contact. Additionally, a second part of the first contact plate projects away from the cam and has a flat surface which is rotated by 90.degree. with respect to the flat surface of the first part, and which serves as a terminal for a plug-in connector.
