摘要： 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.

摘要翻译： 用于断开开关的三件式模制塑料外壳，由通过注射成型工艺单独制造的基座，盖子和门组成。 基座具有与门上的整体模制的搭扣配合的整体模制的延伸片，以允许外壳被挂锁。 两部分铰链，其中铰链的一部分与盖一体地形成，并且剩余部分与门一体地形成，允许门以铰链状的方式组装到盖上。 电气部件附接到基座的内部，并且基座通过螺钉固定到盖上。 当隔间解锁时，螺钉只能从门后方进入。 除了提供在锁门后面防篡改的断开开关，模制塑料外壳是防水和环境安全的。
