Rotary relay contactor

A contactor with a rotary actuation system, the contactor with the rotary actuation system comprising:

• a plurality of switching devices configured to switch a plurality of electrical circuits;
• a plurality of cam followers each operably coupled to one of the plurality of switching devices, wherein each cam follower of the plurality of cam followers is configured to actuate a switching device of the plurality of switching devices;
• a cam mechanism, the cam mechanism pivotally attached to a point rotation, the cam having a perimeter and plurality of lobes about the perimeter, the cam in operable communication with each cam follower of the plurality of cam followers such that upon rotation of the cam mechanism, each cam follower engages a lobe of the plurality of lobes, it causes each cam follower to actuate the respective switching device of the plurality of switching devices;
• an actuator in operable communication with the cam mechanism, the actuator responsive to a control current and operable to rotate the cam mechanism;
• and
• a controller, the controller in operably communication with the actuator, the controller operable to supply the control current the actuator.
