A governor switch apparatus including a governor mechanism to be driven at various speeds of a rotary element and a switching mechanism to be actuated by the governor mechanism. The switching mechanism comprises a seesaw lever to be actuated at its central portion by the governor mechanism, a first switching device connected with a first end of the lever and provided with a first normally open switch, a second switching device connected with a second end of the lever to be assembled symmetrically with the first switching device and provided with a second normally open switch, a stopper for blocking the movement of the first end of the lever after closure of the first switch, and a spring for normally biasing the second end of the lever against actuating force exerted on the lever to close the second switch after the closure of the first switch.
