Abstract
The secondary cover of a molded case electric power switch housing is removably secured in place to enclose cavities in a primary cover for auxiliary devices by an attachment assembly. The attachment assembly includes one or more studs having a first end section with self-tapping threads which fix the studs to the molded primary cover with a second end section having a conventional screw thread projecting outward from the top face of the primary cover. The attachment assembly also includes fasteners in the form of nuts rotatably captured in mounting holes in the secondary cover. Each nut includes a head configured for grasping by a tool and an integral cylindrical collar which extends through the associated mounting hole in the secondary cover. The nuts are retained in place by an outward flair on the free end of the collar. The nuts are provided with a central bore with a thread complimentary to the thread on the second end section of the stud so that with the secondary cover positioned over the primary cover, the nuts are rotated to engage the threads on the stud and thereby firmly secure the secondary cover over the primary cover. The durable studs and nuts experience little wear over repeated installation and removal of the secondary cover.
