Abstract
An electrical device to be mounted on a support includes a housing having an inner part and an outer part secured to one another. The housing is mounted on the support in a position in which the outer part of the housing is accessible. A cover plate is provided for obscuring the view of at least a portion of the housing and surrounding areas of the support. The cover plate has at least one through opening in it. The cover plate is secured to the housing by a screw passing through the opening and an aperture. The screw engages the thread of a threaded bore when the device is fully assembled. The outer housing part includes webs at or within the opening for engaging the shank of the screw and temporarily holding it, and with it the cover plate, in their proper positions prior to engagement of the shank thread with the bore thread.
