Claims

[Scope of utility model registration request]

a housing 18 attached to the circuit board 2;
a rotor 19 that is rotatably housed in the housing 18 and provided in the central portion through the receiving groove 24 of the force transmitting member 13; a pair of fixed contact pieces 20a and 20b that are housed and fixed in the housing 18; a movable contact piece 21 fixed to the rotor 19, and an inner wall surface 22 of the housing 18 facing the rotor 9;
Tip semicircular portion 23 of resilient arm portion 23 of rotor 9
By providing step portions 22a and 22b for engaging and disengaging the movable contact piece 21, by rotating the rotor 19, the movable contact piece 21 moves in and out between the fixed contact pieces 20a and 20b, and the fixed contact pieces 20a and 20b are electrically connected. A switch device that connects or disconnects the tip end semicircular portion 23a of the resilient arm portion 23 with the stepped portion 22b during electrical connection, and press-fits the tip semicircular portion 23a of the resilient arm portion 23 with the stepped portion 22b for electrical isolation. .
