Abstract

1,257,141. Relay contact spring assemblies. SIEMENS A.G. 6 March, 1970 [10 March, 1969], No. 10786/70. Heading H1N. A contact spring assembly of an electromagnetic relay has an angle of at least 10 degrees between the free parts of the fixed and movable contact spring blades. As shown, the fixed contact blades 4c engage support plates 4b near the contact ends and co-operate with a movable blade 4d which enters a conical or convex surfaced recess 9a in an operating component 9 on an armature extension 8. The support plates may conform to the shape of the fixed contact blades.
