Dual power automatic transfer switch mechanism

A dual power automatic transfer switch mechanism, comprising:

• a switch housing;
• a first spring;
• a second spring;
• a first pin disposed on a first movable contact corresponding to a first power supply, the first spring acts between the first pin and the switch housing;
• and
• a second pin disposed on a second movable contact corresponding to a second power supply, the second spring acts between the second pin and the switch housing;
• a first driving disk is configured to actuate the first pin moves between a first power-on position and a first power-off position;
• a second driving disk is configured to actuate the second pin moves between a second power-on position and a second power-off position;
• wherein the first driving disk and the second driving disk are configured to rotate synchronously such that:
• when the first pin is in the first power-on position, the second pin is in the second power-off position;
• when the first pin is in the first power-off position, the second pin is in the second power-on position;
• or
• when the first pin is in the first power-off position, the second pin is in the second power-off position.
