The knob has an accommodating chamber in its inside. A presser is accommodated within the chamber and biased downward by a spring. A pair of contact blades are positioned under the presser. Each of the contact blades is formed at its central portion with a V-shaped portion and inclined surfaces extending toward the right and left directions. The inclined surfaces are further extended to form contact portions. There is formed with a step between the inclined surfaces and the contact portions, so that a first step of operation and a second step of operation of the knob can be made without mistake. Stationary contacts are positioned corresponding to the contact portions. It also has a pair of contact holders. Each of the holders has a supporting piece folded upward from its one side. The supporting pieces contact the under surfaces of the inclined surfaces. A two way solenoid is connected to the knob to attract it in the both directions.
