The purpose of the utility model is achieved in that a kind of large current interruption device combined socket and switch; Comprise the tie breaker of forming by socket and switch; Be characterized in that socket is that a side is provided with the rectangular insulator that A lets out the electric arc groove, socket one end is provided with and patches port, and the other end is provided with A slot and B slot; Grafting B contact in the grafting A contact in the A slot, B slot; Switch is the rectangle blind plug that an end is provided with C contact and D contact, and switch one side is provided with B and lets out the electric arc groove; The switch socket joint patches in the port socket, and C contact and D contact are pegged graft with A contact and B contact respectively and realized that the conducting of big electric current, its A let out electric arc groove and B and let out the electric arc groove and be superimposed as circuit breaker and let out the electric arc hole.

Said A contact is the conduction inserted sheet that is provided with A plug receptacle, A leg and A limited bayonet, clamp on the A plug receptacle A shell fragment and with the A leg be the right angle setting.

Said B contact is the conduction inserted sheet that is provided with B plug receptacle, B leg and B limited bayonet, clamp on the B plug receptacle B shell fragment and with the B leg be the right angle setting.

The utility model compared with prior art has higher reliability; That satisfies switch when plug lets out the electric arc requirement, can fool proof, and perfect heat-dissipating; Solved the connectivity problem of killer switch and pcb board; Improved the circuit performance of big current delivery greatly, and simple for assembly process, be user-friendly to.
