Abstract

1,046,532. Arcing preventing in switches. GOSUDARSTVENNY INSTITUTE PO PROEKTIROVANIU I ISSLEDOVANIUVZRUVOBEZOPASNOVO ELEKTROOBORUDOVANIA. Jan. 21, 1964, No. 2562/64. Heading H2B. A switch operated by a solenoid 1 against spring bias 11, 12 has two pairs of contacts 2, 3 connected in parallel each having in series therewith a solenoid 7, 8 and a rectifier 4, 5 arranged to hold the contacts closed against the bias after the operating solenoid is de-energized and until they are carrying no current, the contacts thus being opened in successive half-cycles of the A.C.
