Abstract
A three-piece molded plastic enclosure for disconnect switches consisting of a base, cover, and door individually fabricated by means of an injection molding process. The base has integrally molded extension tabs cooperating with an integrally molded hasp on the door for allowing the enclosure to be padlocked. A two-part hinge wherein part of the hinge is integrally formed with the cover and the remaining part is integrally formed with the door allowing the door to be assembled to the cover in a hinge-like fashion. Electrical components are attached to the interior of the base and the base is secured to the cover by means of a screw. The screw is only accessible from behind the door when the compartment is unlocked. Besides providing a disconnect switch that is tamper-proof behind a locked door, the molded plastic enclosure is water-tight and environmentally secure.
