A toggle linkage for operatively connecting the motor starting switch to the centrifugal actuator is included as a part of this motor starting switch, and it includes a slider for opening and closing one or more sets of contacts within the starting switch housing movable in the same direction as the actuator member of the centrifugal actuator, and a lever pivoted to the switch housing and engageable by the centrifugal actuator. The slider is privotally connected to the lever so that upon the centrifugal actuator pivoting the lever, the slider is moved to open or close the contacts.
