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 which is disposed to correspond to a first power supply, the first spring acts between the first pin and the switch housing;
• and
• a second pin which is disposed to correspond 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,
• wherein the first driving disk and the second driving disk are configured to be axially disposed on a same drive shaft and driven by the same drive shaft to rotate synchronously about a rotation axis of the drive shaft,
• wherein the first spring directly acts on the first pin, and the second spring directly acts on the second pin, and the first spring and the second spring are located at one side of the drive shaft,
• wherein the first spring is directly connected to the first pin and acts directly on the first pin, and the second spring is directly connected to the second pin and acts directly on the second pin;
• and wherein when the first pin is in the first power-on position and the second pin is in the second power-off position, or when the first pin is in the first power-off position and the second pin is in the second power-on position, the first spring and the second spring are located on one side of the drive shaft.
