Abstract
A push switch, fixed on the back of a rotary variable resistor, comprises a stationary contact formed on the bottom of an insulating housing part, a movable contact of convex form, and a drive means formed on the end of an arm integrally molded with another part of the insulating housing. The drive means is mounted to the end of the operating shaft, and pushes the central part of the movable contact. Normally, the movable contact during axial movement of the operating shaft does not make contact with the stationary contact, when the operating shaft is pushed, the movable contact however, makes contact with the stationary contact. When pressure on the operating shaft is removed, the movable contact is returned to its original position by the resiliency of the movable contact and the arm.
