Abstract
7438. Davies, E. T. April 8. Switches.-In tumbler and like switches in which the cover is secured to the bridge-piece by means of a screwed ring operated by a spanner or key, the bridge-piece c attached to the base a of the tumbler switch is formed with the usual externally-screwed boss c', and also with a flange c<3> which serves as an abutment shoulder. An internally-screwed ring of two diameters is screwed, by means of a spanner or key engaging with transverse slots e<3> or otherwise, on to the boss c<2> and hard down against the flange c<3>. The cover g has upon it a resilient ring piece g<2>, comprising a series of spring tongues, to serve as a mechanical contact between the cover and the ring e. This ring screws completely within the recess g<5> in the cover, which is held by the resilient springs but which may be revolved by the hand, and only removed by means of the special key, operating the ring e. In a modification, Fig. 4, the screw e is provided with resilient pieces in place of the resilient pieces on the cover.
