ABSTRACT:
An flat casing (10) exhibiting a convex curvature to the outside on all sides, is slid onto the projection (1a) of a base (1). The casing (10) protects a contact device anchored in the base (1). The base (1) protrudes with the peripheral brackets (1b), formed on two sides of the base (1), beyond the projection (1a) into the casing (10) and supports the casing (10) from the insides A U-shaped carrier plate (4) is anchored with its arms (4a) in the brackets (1b). The carrier plate (4) is furnished with longitudinal edges (6), which are bent off at right angles outside of the anchoring, and the longitudinal edges (6) rest force-matchingly at the interior wall of the casing (10).
