Abstract
686,517. Shock-proof switches. ALLMANNA SVENSKA ELEKTRISKA AKTIEBOLAGET. Aug. 29, 1951 [Sept. 30, 1950], No. 20356/51. Class 38 (v) In a shock-proof switch wherein the current for each pole passes through two contact pairs in parallel and any shock tending to open one pair will tend to close the other pair, a rotary shaft 5 carries two pairs of contacts 3, 4 adapted to bridge simultaneously fixed contacts 1 and 2 respectively. Contacts 1, 2 are permanently connected by conductors 6, 7 as shown so that current from a lead 8 proceeds in parallel through bridges 3, 4 to a lead 9.
