Abstract
The invention concerns a switching appliance comprising several main dual cut-out poles provided with fixed contacts housed in an arc box and mobile contacts located on a mobile contact-holder (30). The latter is equipped, for the main contacts, with main housings (31) aligned transversely to the direction (X) of displacement of the contact-holder (30), and, for the auxiliary contacts, secondary housings (32) aligned transversely to the direction (X) and located in front of the main housings (31). The contact-holder comprises between the main housings and the secondary housings a vertical insulating wall (35). The arc box consists of two half boxes (20, 40) assembled in a horizontal plane, so that one of the two halves provides guiding elements and stop elements for the contact-holder (30).
