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.
