Abstract
299,841. Schapringer, G. Nov. 2, 1027, [Convention date]. Couplings combined with switches.-Switches of the two-part rotary type, of which the upper part carries the switch device whereas the lower carries only the members for securing the switch to the base and for connecting it up to the leads, have the two parts removably connected together by connections usually employed with incandescent lamps. Replacement of a wornout switch can then be effected without trouble and without making the circuit dead.
