Abstract

The relay comprises a base body ( ), a coil ( ), a core arrangement ( ), an armature ( ) and a contact system. The contact spring ( ) is configured as an arc and arranged to be connected with the armature ( ) in such a way that it is subjected to uniform, low mechanical loading. As a result a material can be used for the contact spring ( ) which presents high electrical conductivity, so that the forward resistance of the relay is reduced. The contact spring ( ) and armature ( ) are arranged in such a way that a relay with a compact structure can be obtained.
