<p>New cover assemblies for electrical fixtures in buildings allow conventional outlets and (toggle) light switches to be cheaply converted into a variety of different designs and/or colours without changing the electrical infrastructure of the fixture. The cover assemblies comprise a cover plate with an appropriate number of orifices, each orifice covered by a slider so that the whole assembly shields the standard parts of the fixtures normally visible in building interiors.</p> |
