ABSTRACT:
A three-pole switch arrangement has for each pole a pole housing, onto which collar-shaped extensions, protruding on the underside, are formed. Provided in the extensions are screw holes, the graduation of which corresponds to the screw coupling, by which the mechanism housing has been screwed to the pole housing. The outer switch poles are oriented outwardly by one graduation and are fastened to the frame by means of screws. Counter to this inclined position, the mechanism housing, rotated by one graduation, is screwed onto the pole housing. It is consequently possible to use the same parts for all three switch poles, and also to transport the switch arrangement pole-by-pole.
