Abstract

677,316. Electromagnetic relays. KUHNKE, H. Dec. 1, 1950. [Dec. 1, 1949] No. 29531/50. Class 38 (v). The contact springs of a relay are arranged in tiers, each tier comprising at least two arcuate-shaped movable contact springs such as 10, 15, fixed at one end 39 and having projecting portions 16, 17 engagable by an actuating member such as 7 arranged on a shaft 6 movable longitudinally by the electromagnet. By this means it is brought into or out of engagement with arcuate fixed contacts. In the form shown there are three actuating members axially spaced along the shaft 6 and co-operating with three tiers of contacts.
