Abstract:
The present application provides a switching device, comprising a crank slider assembly, input and output transmission assemblies, and a contact assembly.

A slider of the crank slider assembly moves to H2 when the swing rod moves to Z2, and moves to H1 when the swing rod returns to Z1. When the slider moves to H2, an output end of the output transmission assembly drives the contact assembly to be closed. When the slider moves to H1, the output end drives the contact assembly to be opened.
