ABSTRACT:
The switch of the invention includes, for each pole, an insulating case having two lateral dividing walls one of which forms part of an open pole housing and the other belongs to a closure element of the case. Each pole includes a contact opening mechanism with which is associated a common transmission piece for coupling said pole with an adjacent pole. This piece is mounted for rotation in a bearing formed in the lateral dividing wall of the case. It has at one end a male coupling element and at a second end a female coupling element, these elements being of complementary shapes for allowing engagement of adjacent and coaxial coupling pieces by fitting together.
