ABSTRACT OF THE DISCLOSURE Single-pole switches are customary in middle voltage networks in the U.S.A. and in other countries with similar distribution systems. A switch safety device acts as a? single- pole switch element, such a switch device is usually combined with an extinguishing device for normal load currents. In order to improve safety, a plurality of conventional load-disconnec- ting switches are arranged in a common frame, and each load-dis- connecting switch permits individual switching. This is made possible by hubs arranged on a common shaft within the common frame. In each instance, these hubs constitute the connection to a load-disconnecting switch and an associated drive. In addi- tion, each load-disconnecting switch may be provided with a holder, into which an HH-type fuse can be inserted.
