Claims

[Scope of utility model registration request]

It consists of a case, a board that fits into the bottom of the case, and a rotary sliding object that rotates around a rotating shaft that is arranged between the board and the case and engages the board and the case, and the upper surface of the board A resistor pattern of a variable resistor, a current collecting conductor pattern, etc. are formed on the
In a rotary variable resistor, the rotary sliding type object is provided with a sliding piece that slides on a resistor pattern and a current collecting pattern on the upper surface of the substrate, and the rotary sliding type object is provided with an operating protrusion for driving a switch. Additionally, a switch on the substrate includes a movable contact operated by the actuating protrusion and a fixed contact abutting the movable contact, and a rotation stopper that locks onto the rotating sliding type object and stopping the rotation of the rotating sliding type object. A member is provided, and the arrangement relationship between the operating protrusion, the switch, and the rotation stop member is such that the rotating shaft of the rotating sliding type is rotated from the stop position in a predetermined direction, and the operating protrusion abuts the movable contact and crosses the inverted position. The switch is turned ON at a point, the rotary sliding object is rotated in the opposite direction, the operating protrusion contacts the movable contact, and the switch is turned OFF at a point beyond the reversal position. A rotary variable resistor with a switch, characterized in that the rotary variable resistor comes into contact with a rotation stopping member to stop its rotation.
