Safety set of relay springs - with each set placed in compartment of insulating block, with three walls made of parts of block and third wall of case

摘要

The spring set provides security against leakage currents, ensures high breakdown strength and reduces interaction between contact spring sets. It consists of an insulating block holding active and passive contact springs operated by at least one operating element. Contact springs (4, 5) allocated to each other are mounted in entirely closed chambers (9) in the insulating block (1). Its one wall consists of a surface of a protective case a second wall of a partition in the insulating block (1), and the third and fourth walls of side walls (7) of the block (1) perpendicular to the partition.
