Abstract
A motor starting switch mountable on an electric motor and actuatable by a centrifugal actuator for energizing the starting winding of the motor during start up of the motor and for deenergizing the starting winding or other circuits upon the motor attaining a desired operating speed. 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.
