Road enables the heat that short circuit scheduled production is given birth to quickly to be discharged.The Wen Sheng for reducing short circuit row, ensure that the property of electrical rotary switch
Energy.
Technical solution
In order to achieve the above technical purposes, the short circuit knot of a kind of multipole electrical rotary switch of the utility model design
Structure, it includes the block pedestal being at least superimposed, and static contact is housed in the pedestal, and the static contact is connected using short circuit row
It connects, it is characterised in that:In the short circuit round of the pedestal, both ends are quiet with neighbouring two layers respectively for the short circuit socket
Contact connects, and the short circuit round is in communication with the outside using the convection holes on the pedestal.
Further, the short circuit row is provided at both ends with terminal screw installation via.
A kind of contact module including above-mentioned short-circuit structure, it is characterised in that：Moving contact is mounted in the moving contact of the pedestal
It can rotate around the axis in mounting groove, the shaft concatenates the moving contact in pedestal.
Further, the moving contact includes moving contact pedestal, and the passive contact cover board of moving contact conductive sheet is fitted in described dynamic
In contact pedestal.
Further, the static contact includes contact site and wire connecting portion, and the contact site and wire connecting portion are mutually perpendicular to.
Advantageous effect
The short-circuit structure and contact module of a kind of multipole electrical rotary switch provided by the utility model increase short circuit row
With extraneous interface channel, the heat that short circuit scheduled production is given birth to is enable quickly to be discharged.The Wen Sheng for reducing short circuit row, ensure that rotary electric
The performance of air cock.
