Title: PUSH SWITCH
Abstract:
An operating body (2) is provided with first ratchet teeth (24A-24D). A vertically movable cam member (4) has first cam protrusions (45A-45H) arranged in the circumferential direction. A rotatable cam member (5) has: second ratchet teeth (54A-54H) engaging with the first ratchet teeth (24A-24D); and second cam protrusions (55A-55H) engaging with the first cam protrusions (45A-45H). The contact sections of a movable contact member (6) come in contact with and separate from stationary terminals (76A-76F), which face the contact sections, as the rotatable cam member (5) rotates. An elastic member (3) is disposed between the operating body (2) and the vertically movable cam member (4). The rotatable cam member (5) is configured so as to rotate a first predetermined angle when the operating body (2) is pressed so that the first ratchet teeth (24A-24D) of the operating body (2) and the second ratchet teeth (54A-54H) of the rotatable cam member (5) will engage with each other. The rotatable cam member (5) is configured so that, when the operating body (2) is released from the pressing, the pressing force of the elastic member (3) will cause the vertically movable cam member (4) to press on the rotatable cam member (5) to thereby rotate the rotatable cam member (5) a second predetermined angle.
