A system and method for an automatic transfer switch comprising a fixed contact (), a first oscillating rod () communicatively and operatively connected to a first movable contact (), a second oscillating rod () communicatively and operatively connected to a second movable contact (), a link rod () communicatively and operable connected to the first and second oscillating rods (), a guide plate (), and a permanent magnetic actuator () comprising a first end and a second end communicatively and operatively connected to the link rod () via a third oscillating rod (), wherein the first end being energized independently of the second end. The automatic transfer switch is operable to position the guide plate () based at least on a permanent magnetic force applied to the first end or the second end of the permanent magnetic actuator.

Automatic transfer switch with permanent magnetic actuation

A system and method for an automatic transfer switch comprising a fixed contact, a first oscillating rod communicatively and operatively connected to a first movable contact, a second oscillating rod communicatively and operatively connected to a second movable contact, a link rod communicatively and operable connected to the first and second oscillating rods, and a guide plate. The automatic transfer switch is operable to position the guide plate based at least on a state of a solenoid. A permanent magnetic actuator communicatively and operatively connected to the link rod via a third oscillating rod is operable to rotate the first oscillating rod or the second oscillating rod based at least on the position of the guide plate.
