ABSTRACT:
In 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 engageable with a first end of the lever and provided with a first normally open switch, a second switching device engageable with a second end of the lever to be assembled symmetrically with the first switching device and provided with a second normally open switch, and a stopper for blocking the movement of the first end of the lever after closure of the first switch. The first switch is closed prior to the second switch due to a difference between the resilient forces given to the first and second switching devices respectively.
