Description
Technical field
The present invention relates to circuit conversion technical field more particularly to a kind of combined circuit change-over switches.
Background technique
Bomb shackle used at present only has machine insurance function, does not have electrical insurance function, to prevent because of maloperation
Hanger is caused surprisingly to be launched, hanger circuit need to have ground power-off insurance function.
Summary of the invention
Technical problem solved by the invention is to provide a kind of combined circuit change-over switch, to solve above-mentioned background skill
Disadvantage in art.
Technical problem solved by the invention is realized using following technical scheme:
A kind of combined circuit change-over switch, including the electrical insurance shell being fixed by screws on hanger, wherein electricity
Microswitch is provided in gas insurance shell, microswitch bottom is provided with microswitch contact, and setting is in electrically insurance shell
Outer touch part one end is connect with setting in electrically insurance intracorporal axis one end of shell, and the axis other end is connect with elastic parts one end,
The elastic parts other end is fixed on electrical insurance shell, and the touch part other end is provided with the pin for being inserted into ground safety plug
Hole；The groove for placing steel ball is provided on axis simultaneously, steel ball and microswitch contact connect.
In the present invention, electrical insurance lid is electrically provided on insurance shell.
In the present invention, microswitch is mounted in electrical insurance shell by fixed pin.
In the present invention, elastic parts includes spring.
In the present invention, groove at two is provided on axis.
In the present invention, after hanger hangs store Combinations, by the pin hole of ground safety plug insertion touch part, ground is insured
Pin touching touch part, touch part and motion compresses spring before axial direction, the steel ball on axis are jacked up upwards, steel ball touches microswitch
Contact is simultaneously connected with microswitch contact, and microswitch starts work, and hanger circuit disconnects, and realizes that the open circuit of circuit is protected
Danger；Then extract ground safety plug out, axis return under the action of the spring, steel ball and microswitch contact separation are fallen after rise to groove, micro-
Dynamic switch stops working, and hanger circuit is connected, and effectively prevent causing hanger surprisingly to be launched because of maloperation.
The utility model has the advantages that the present invention by ground safety plug touch touch part drive axial direction before motion compresses spring,
The elastic force of spring acts on lower steel ball and microswitch contact connects, and microswitch starts work, and hanger circuit disconnects；Extraction
Ground safety plug, return, steel ball and microswitch contact separation are fallen after rise to groove axis under the action of the spring, and microswitch stops work
Make, hanger circuit is connected, and effectively prevent causing hanger surprisingly to be launched because of maloperation.
