摘要
A multi-pole low-voltage power switch designed with several switching chambers per pole and a common switching shaft which acts for the pole units is formed by the switching chambers. The switching shaft is made up of shaft sections which correspond to the pole units. While the central shaft section has central pins and levers, the peripheral shaft sections are fitted with levers and have central apertures in which the pins engage. Bolts which pass through the levers are used to couple the shaft sections together. The pole units rest on a support which is dimensioned to accommodate the maximum width of the pole units and to allow for possible variations in their dimensions. Side walls of the correct dimensions for a pull-out rack enclosed the supporting framework of the power switch on each side.
