SWITCHING DEVICE

摘要

The present invention provides a switching device, which switching device comprises a turntable fitted on a rotary shaft, said turntable can be driven to rotate around said rotary shaft, thereby bringing a switch contact mounted on said turntable to open or close, wherein said turntable comprises a primary turntable and a secondary turntable; said switch contact is fitted on said secondary turntable, so that when said primary turntable rotates, it can bring said secondary turntable to rotate, thereby driving said switch contact to open or close; and said secondary turntable can be operated through a testing switch mechanism constructed by a linking rod mechanism, which makes it possible to rotate independent of said primary turntable and bring said switch contact to open or close. The switching device proposed in the present invention is mainly applicable to low-voltage switches, such as accessories of electrical appliances, in particular alarm switches or auxiliary switches, which can make the switch contact in a switching device open or close without interrupting the primary switch.
