摘要： The present disclosure relates to a dual power transfer switch including a main shaft, a first drive disc integrated with the main shaft and a second drive disc arranged coaxially with the first drive disc. The first drive disc includes a first stop surface, at least one first pin and at least one first pin hole. The first stop surface protrudes from a surface of the first drive disc. The at least one first pin is fixed on the first drive disc. The second drive disc includes a second stop surface, at least one second pin and at least one second pin hole. The second stop surface protrudes from a surface of the second drive disc. The at least one second pin is fixed on the second drive disc. The at least one first pin cooperates with the at least one second pin hole, the at least one second pin cooperates with the at least one first pin hole, and the second stop surface abuts against the first stop surface so that the first drive disc and the second drive disc rotate together in a circumferential rotation direction.

摘要： The invention provides a switching mechanism for a dual power supply transfer switch. The switching mechanism has a switching assembly, which includes a driving plate, a driving rod, an actuator and an auxiliary mechanism. The driving plate includes an arc-shaped driving groove. The driving rod extends into the driving groove. The auxiliary mechanism includes a spring. The driving plate is able to rotate under an external force. The driving groove bypasses the driving rod when an end of the driving groove does not contact the driving rod, and the driving groove pushes the driving rod to rotate over a first angle and urges the spring to deform when the end of the driving groove contacts the driving rod. The spring recovers and drives the driving rod to rotate over a second angle after the spring having passed a dead point, thus causing the actuator turning on or off a first power supply. The switching mechanism also includes another switching assembly for switching a second power supply. Further, the present invention also provides a dual power supply transfer switch including said switching mechanism.
