Sealed electrical apparatus e.g. two-way switch, for e.g. wall, has tabs locking grip on rib and generating pressure effort of plate on case compressing joint, where cover and pate are formed of single part by molding of plastic material

摘要

The apparatus (1) has a peripheral sealing joint interposed between a frame shaped plate (20) and a parallelepiped shaped case (10), and the plate adjusted on a front face of the case. A cover (30) closes a central opening (21) delimited by the plate. The cover has tabs (31) inserted between a plate`s locking grip (24) and a small length (13B) of a case`s L-shaped wall for locking the grip on a complementary locking rib and for generating a pressure effort of the plate on the case compressing the joint. The cover and the pate are formed of a single part by molding of plastic material.
