Abstract

A housing for electrical equipment, for insertion into an installation opening of a switching panel, includes a housing body which can be pushed through the installation opening in an insertion direction and a covering wall connected to the housing body which extends generally transversely to the insertion direction. The covering wall includes a collar which projects outwardly beyond the housing body in a direction which is transverse to the insertion direction, such that the collar limits insertion of the housing body into the opening. A plurality of lugs are connected to the housing body, and each of the lugs has a free end and is resiliently biased toward an initial position relative to the housing body. The housing body has a pair of side walls, and each of the pair of side walls supports an end of at least one corresponding one of the plurality of lugs at an acute angle thereto. Each free end extends to a location which is adjacent to the collar of the covering wall. Each of the lugs has a toothed detent surface in the vicinity of its free end for securing the housing body within the installation opening. Each of the plurality of lugs has a supporting bar which supports a supp…
