FIG. 4 is a longitudinal sectional view of the rotor in the pushed-in position. In the drawing, 1 is a switch case, 7 is a fixed contact,
12 is a rotor, 14 to 17 are first to fourth inclined parts, 18 is a lock recess, 19 is a cam groove, 21 is a movable contact, 23 is a movable contact, 25 is a spring member, and 26 is a lock protrusion.

Claims

[Scope of utility model registration request]

a switch case; a rotor rotatably mounted on the switch case and moved in the pushing direction by a pressing operation; and a movable contact having a movable contact and rotating integrally with the rotor. and a fixed contact provided on the switch case so as to face the movable contact, and between the rotor and the movable contact, biasing the rotor toward the original position and biasing the movable contact toward the fixed contact. a cam groove having an inclined portion and a locking recess provided on one of the outer circumferential portion of the rotor and the inner circumferential portion of the switch case facing the rotor; a lock protrusion that is fitted into the cam groove and relatively slid along the cam groove as the rotor moves, and the rotor is pushed in from its original position against the biasing force of a spring member. The lock protrusion slides along the slope of the cam groove as the pressure is released, causing the rotor and movable contact to rotate and the lock protrusion to lock the cam groove. The rotor is engaged with the recess to hold the rotor in the pushed-in position, and the movable contact is brought into contact with the fixed contact, and then the rotor is pushed again in the pushing direction from the locked position, and then the pressure is released. As the lock protrusion slides along the slope of the cam groove, the rotor and movable contact are rotated, and the rotor is returned to its original position by the biasing force of the spring member, and the movable contact is rotated. A switch device characterized in that a movable contact is separated from a fixed contact by movement.
