The invention relates to a fuse type load disconnection switch. A spring energy storage operating mechanism is composed of a handle, a support, a main shaft, a shaft sleeve, a spring leaf in the shaft sleeve, a fastener, stop blocks, a pull bar and the like. A switch body is composed of an insulating base plate, a support member, an arc extinguishing shield, main contacts, steel spring rings (or sheet spring steel), a crossbeam, a blade assembly, flash barriers, a guide rail and the like. The handle is pushed or pulled to drive the main shaft, the main shaft drives the spring leaf in the shaft sleeve, energy storage of the spring in the shaft sleeve is completed when the main shaft rotates to a certain position, under the elastic force of the spring leaf, the shaft sleeve rapidly rotates to drive a link rod welded to the shaft sleeve, the link rod drives the pull bar fixed to the crossbeam of the switch, and the pull bar drives the crossbeam and the blade assembly fixed to the crossbeam to slide rapidly up and down in the guide rail to realize rapid closing and opening of the switch.
