Claims

[Scope of utility model registration request]

A rotary variable resistor having a rotating shaft for varying resistance in the center, a movable contact piece that operates in conjunction with the rotation of the rotating shaft, and a switch board having a fixed contact pattern that slides into contact with the movable contact piece. A rotary switch is provided, and the rotary switch is arranged so as to be turned on when the rotary shaft rotates beyond a point that makes the resistance value of the rotary variable resistor a minimum value or a maximum value. A variable resistor with a switch, further comprising a spring that rotates the rotary shaft by a predetermined amount in a direction to turn off the rotary switch when the rotary shaft is opened while the rotary switch is on.
