。2. Description of the Related Art Conventionally, this type of automatic return type knob switch has been constructed as shown in FIG. In FIG. 2, 1 is a rotor, and 2 is a spring for applying contact pressure. Rotor 1 has hole 1 for spring 2! There is an L. 3 is a movable contact, and 4 is a fixed contact. 5 is a torsion coil spring for automatic return. A spring 2 is used to press the movable contact 3 against the fixed contact 4 in order to generate the contact pressure of the contact, and when the rotor is rotated, the movable contact 3 and the fixed contact 4 are switched and the rotating force is removed. The rotor returns to its original position by the torsion coil spring 5 for return, thereby automatically returning the contact point.
