Abstract

347,539. Secret contact-combination switches. ZINTER, R., 7, Lothar Bucherstrasse, Steglitz, ANTIFURTUM AUTOAPPARATE - BAU., GES., 12, Prinzenstrasse, and MASCHINEN-AGENTUREN, GES., 25, J�gerstrasse, all in Berlin. July 1, 1930, No. 19945. [Class 38 (v).] An adjustable combination switch 18 comprises a pair of contact rings 13, 13<1> swept by a pair of arms 16, 17 loosely coupled so that two successive movements o f t h e spindle 19 are required in order to bring both arms into contact with insulated segments 14, 14<1> for closing one circuit and breaking another.
