Abstract

158,234. Messer, A., (Assignee of Herold & Co.). Jan. 23, 1920. Switches, quick-action.-In switches in which steel balls are used, means are provided for varying the internal connections. In the construction shown, the balls o are guided in holders q attached to the terminals and are pressed against the rotary disc C by springs p, The disc is fitted with contact sleeves e which engage the balls in certain positions. The contact sleeves e are attached to a brass lining on the lower face of the disc, the lining being divided into three parts i, k, l, separated by insulating ribs f, g, h. Screws m, n may be inserted into the insulating ribs for contacting between adjacent plates i, l and l, k respectively, for varying the internal connections of the switch, which may thereby be converted into a multiple-way switch, with or without an " off " position. An opening, normally closed by a screw v, is provided in the base B to enable the switch connections to be varied.
