Claims

[Scope of utility model registration request]

While a plurality of fixed contacts are attached to an insulator fixed to the switch case, a holder is provided that is built into the case so that it can be raised and lowered integrally with a knob protruding outside the case and is biased by a return spring, and a holder is provided on one side of the holder. A movable contact that comes into contact with and separates from the above fixed contact is provided so that depending on the position of the holder, the movable contact comes into contact with any fixed contact and the multi-stage switch is selectively turned on, while the other side of the holder or the switch case side An uneven portion is formed on one side of the holder, and a back spring whose one end is biased in one direction and supported is provided on the other side, and the tip engaging portion of the back spring moves the concave movement passage formed in the uneven portion to raise and lower the holder. The back spring engaging portion locks the holder at the lock position formed in the moving passage, and at the lock position, the movable contact and the fixed contact come into contact and the switch is locked in the on state. and the back spring engaging portion engages with a predetermined position of the moving passage (the switch is turned on while the holder is pressed).
