Claims (1)

[Claims for Utility Model Registration] 1. A plurality of unit switches each having bushings fixed to their upper parts are installed in parallel, and the upper bushings of adjacent unit switches are electrically connected by a conductive member. In the multi-circuit switch, the upper bushing of each switch has a terminal projecting upward, and these adjacent terminals are removably connected to each other by a conductive bar having approximately the same length between the terminals. A connection structure of an upper bushing in a multi-circuit switch characterized by the following. 2. In a multi-circuit switch in which a plurality of unit switches each having bushings fixed to the upper part are installed in parallel, and the upper bushings of the adjacent unit switches are electrically connected by a conductive member, each of the above-mentioned The upper bushing of the switch has a terminal projecting upward, and these adjacent terminals are removably connected to each other by a conductive bar having approximately the same length between the terminals, and is attached to the bushing. An insulating cover consisting of a vertical part that removably fits together and a horizontal part that covers the conductive bar and the terminal is provided, the horizontal part is divided between adjacent bushings, and the divided parts are separably connected. A connection structure for an upper side bushing in a multi-circuit switch, characterized in that:
