Abstract

450,382. Switch contacts. PORZELLANFABRIK KAHLA, Kahla, Thuringia, Germany. Dec. 5, 1935, No. 33761. Convention date, Dec. 6, 1934. [Class 38 (v)] In an electric switch, such as a rotary switch for wireless apparatus, the contacts 14 consist of coatings of noble metal such as silver and platinum burned on to a projecting strip 15 of inorganic insulating material by the method employed for decoration purposes in the ceramic industry. The insulating material is preferably low loss ceramic material. In the form shown, a cam roller 19 depresses a series of contact springs 11 into engagement with the fixed contacts 14.
