Multi-functional, flush-fitting electrical mechanism

Abstract

Consisting of a casing (), affixed to the supporting ring (), equipped with an external operating key (), whose hollow interior features interchangeable sets of contacts (and), in order to fulfill the following applications: single-pole switch, illuminated single-pole switch, single-pole switch with pilot light, bell-push, illuminated bell-push, two-way switch, illuminated two-way switch, two-way switch with pilot light, double-pole switch, double-pole switch with pilot light, crossover switch and illuminated crossover switch. The casing.(), when it houses four contacts, features four lateral mounts (), and for two or three contacts, three mounts (). The rocker () transmits the pressure exerted on the key () to a swinging contact (), and furthermore features two pivots () in the embodiment with two swinging contacts () and a single pivot () in that of a single swinging contact (). The closing contact () of the crossover switch is obtained by means of soldering, being equipped with a separator () as protection against arcing. A system for fixing the contacts and a method for locking the fast connection keys () are foreseen, as is the particular arrangement of the pilot light, (), whose contacts, by turning the same from one position to another, allow its function to be changed between that of pilot light and illumination; another characteristic being elements () and (), which cause the light to be reflected so that it emerges through the visor (), located in the key (). The mechanism may be extracted from the front, with no need to remove the supporting ring ().
