摘要： An automatic transfer switch includes a motor and a drive shaft rotatable by the motor. The automatic transfer switch includes a gear rotatable by the drive shaft. The automatic transfer switch includes a pin attached to, and movable with, the gear. The pin is offset from the central axis of the gear. The automatic transfer switch includes a bracket rotatable around the central axis of the gear and connected to an output shaft. The bracket is rotatable separately from the gear. Upon rotation of the bracket, the output shaft rotates. The bracket has at least a first source position and a second source position and the first and second source positions are different. The automatic transfer switch includes a module connected to the output shaft. The module includes at least one movable electrical contact which moves upon rotation of the output shaft.

摘要： An automatic transfer switch includes a motor and a drive shaft rotatable by the motor. The automatic transfer switch includes a gear rotatable by the drive shaft. The gear has a plurality of teeth offset from a central axis of the gear and the teeth are engageable by the drive shaft. The automatic transfer switch includes a pin attached to, and movable with, the gear. The pin is offset from the central axis of the gear. The automatic transfer switch includes a bracket rotatable around the central axis of the gear and connected to an output shaft. The bracket is rotatable separately from the gear. Upon rotation of the bracket, the output shaft rotates. The bracket has at least a first source position and a second source position and the first and second source positions are different. The automatic transfer switch includes a chargeable motivator that has a first end and a second end. The first end is connected to the pin and the second end is connected to a portion of the bracket offset from the central axis. The chargeable motivator is at least partially charged upon movement of the pin to motivate the movement of the bracket between the first and second source positions. The automatic transfer switch includes a module connected to the output shaft. The module includes at least one movable electrical contact and the at least one electrical contact moves upon rotation of the output shaft.
