摘要： An operation portion and a switch portion of a push button switch are removably coupled. The switch portion includes a contact opening mechanism having a rotatably supported lever and a spring. The lever has one end acting on a part of the operation portion coupled with the switch portion, and the other end acting on a contact switching mechanism of the switching contact unit in the switch portion to open/close the contacts. The spring urges the lever in a fixed rotation direction. The contact switching mechanism is urged to move a movable contact from a standby state position toward an operating state position by the contact opening mechanism when the switch portion is separated from the operation portion. The contact switching mechanism is released from the urging when the switch portion is coupled with the operation portion.
