Claims (1)

[Scope of utility model registration request] Two cams are supported on the switch body so as to be able to slide up and down between a non-press operation position and a press operation position, and are not rotatable around the slide axis. An operating body consisting of operating claws, a pair of engagement grooves adjacent to these operating claws, and continuously protruding around the slide axis, and an urging member holding the operating body in a non-pressing operating position. an operating body biasing and holding means fixed to the switch body, the negative end surface of which is located astride between the inclined cam surfaces of the two adjacent operating claws in a positional relationship around the slide axis; With the downwardly opening engagement recess formed on the inclined cam surface inclined in the same direction as the cam surface, with the inclined cam surface positioned slightly above the inclined cam surface of the operating pawl at the pressing operation position, The engaging recesses are formed at equal angular intervals around the slide axis, and are connected to the engaging recesses through inclined guide surfaces that are inclined in the same direction as the inclined cam surfaces of the engaging recesses. a retaining body whose lowest surface position forms a retaining surface that slopes in the same direction as the inclined cam surface reaching at least the operating claw position of the operating body in the non-press operating position in the vertical direction, and is fixed to the switch body. A movable contact piece that can freely slide up and down between the held first and second terminal members and a switch ON position in which it contacts the contact points of both terminal members and a switch OFF position in which it is spaced downward by a predetermined amount from the contact points. and is interposed between the operating body, the holding body, and the movable contact piece such that it can freely slide vertically and rotatably about the slide axis, and each inclined cam surface of the operating pawl and the engagement recess, and the An operated object has an inclined cam surface that can slide on the inclined guide surface and is provided with a protruding engagement protrusion that can engage with the engaging slope, and an object that urges the operated object upward. an operating body pressing means;
a movable contact piece pressing means for bringing the movable contact piece into contact with the first and second contact members, and when the operating body is returned to the non-pressing position, the retaining protrusion of the operated body is pressed against the operating body. When the movable contact piece is engaged with the engagement groove of the body, the movable contact piece engages the switch O.
When the movable contact piece is biased toward the N position and the engaging protrusion is engaged with the engaging recess of the holder, the movable contact piece is biased and held at the switch OFF position. A bush switch featuring the following.
