Abstract

A switch box for wall attachment with a box-like cabinet body having a rear wall and four side walls, the open side of which body can be closed by a cabinet cover or a cabinet door. Using thin starting materials for the cabinet body, an increase of stability, in addition to the possibility of further attachment locations, can be attained by attaching a mounting angle in each of four corner areas on the internal side of the rear wall. The legs of the mounting angle, provided with threaded mounts, are positioned in a plane parallel to the rear wall and spaced at a distance therefrom. At least one external longitudinal side of a leg is provided with a recess for fixing a support strip which is firmly screwed in the area of the open side of the cabinet body. At least one threaded mount of every mounting angle is accessible by a boring in the rear wall of the cabinet body.
