Small quick air bypass switch

The invention discloses a small quick air bypass switch which comprises an insulating shell and an insulating cover which are fixedly connected through a bolt, one side of the insulating cover is fixedly connected with a cable fixing head, a static copper bar and a soft copper bar are arranged in the insulating shell, and a manual opening mechanism and a pulse electromagnetic limiting mechanism which are vertically distributed are arranged in the insulating shell. One end of the static copper bar is fixedly connected with the insulating shell, the soft copper bar is fixedly connected with the manual opening mechanism, and the other ends of the static copper bar and the soft copper bar extend out of the insulating shell. The bypass switch has the advantages that the overall closing operation speed is high, the service life is long, damage is not prone to occurring, the number of parts used for the bypass switch is greatly reduced, the mechanical structure is simple, the assembly process is convenient, the prod
