1. A push button switch comprising: a base having a plurality of terminals arranged separately from each other on a same circumference; a movable contact brush having a plurality of contact portions arranged on the plurality of terminals; a rotor having cams that bring the plurality of contact portions into contact with or separate from the plurality of terminals, and is supported to be capable of rotating about an axis of the base; an actuator that abuts against a gear provided on the rotor and moves in a direction orthogonal to the axis of the base to rotate the rotor; and a button that abuts against the actuator, moves the actuator by a press-in operation, and restores elastically by a spring force; wherein a mechanism for elastically restoring the button is configured to include: an inclined surface that is arranged in the base; and a spring holder that accommodates a coil spring compressed by the actuator and is pressed against the inclined surface by a rebound force of the coil spring.
