Abstract

Abstract An electrical apparatus is provided with a cabinet which accommodates an electrical device having a control member and a box-shaped member both projecting beyond the circumference of the cabinet. The open control side of the apparatus is closed by means of a reversible front plate which fits over the control member and the box-shaped member. The front plate has a peripheral endless upright wall which renders the apparatus suitable for building into a wall or, upon inverting of the front plate, for mounting against a wall.
