Embodiment Construction

[0016] figure 1 A switch 1 is shown which has four pole housings 2 (four-pole switch). The pole housings 2 are arranged laterally side by side, wherein the inner side walls 10 abut one another. The switching shaft 3 extends transversely through the pole housing 2 and opens and closes switching contacts (not shown) arranged in the pole housing 2 , respectively, depending on the direction of rotation. Two (first) terminal elements 4 in the form of terminal lugs extend outwards through the pole housing 2 on mutually opposite (first) sides 5 transverse to the switching axis 3 .

[0017] Instead of the side wall 10 , a cover plate 6 is provided on the outer side, which extends parallel to the side wall 10 of the pole housing 2 .

[0018] For actuating the switch shaft 3 , a control device 7 is provided on the opposite (outer) side of the switch 1 .

[0019] figure 2 shows the button to remove the pole housing 2 figure 1 switch 1, so the pole housing 2 at the front is visible....

Abstract

The present invention relates to a multipole switch (1) having a plurality of pole housings (2) arranged laterally side by side, the switch comprising a switching shaft (3) for separating switching contacts arranged in the pole housings (2); two first terminal elements (4) which are respectively led outwards on two opposite first side surfaces (5) through the pole housings (2); and two second terminal elements (9) which are respectively led outwards on one of two opposite second side surfaces (8) through the pole housings (2) and contact there with contacts of an electric fuse. To implement refitting of electric wires so as to monitor the fuse, prevent contact with charged components and maintain a necessary dielectric distance, an electric wire channel (11) open at two end portions (12, 13) is arranged on a side wall (10) of each pole housing (2), wherein one end portion (12) is arranged in a region of the terminal element (9), the other end portion (13) is crossed with one of the two first side surfaces (5), and electric wires which can be connected to the contacts of the fuse can be led outwards through the electric wire channel (11).

Description

technical field [0001] The invention relates to a multi-pole switch comprising a plurality of pole housings which are arranged laterally side by side with mutually abutting side walls, the switch having a switching shaft which extends transversely through the through the pole housings and for separating the switch contacts arranged in these pole housings for opening the switch; the switch also has two first terminal elements which are respectively transverse to the switch axis is guided outwards through the pole housing on two opposite first sides; the switch also has two second terminal elements which are each transverse As the switching shaft is guided outwards through the pole housing, it contacts contacts of an electrical fuse which is located below a cap-shaped, electrically insulating cover. Background technique [0002] Multipole switches are known in particular as load disconnectors and consist of a plurality of pole housings which are arranged next to each other, w...
