Abstract (en)
The present invention refers to a magnetic system for an electromagnetic relay, to an electromagnetic relay and to a method for manufacturing same. In particular, the present invention concerns a magnetic system for an electromagnetic relay, wherein said magnetic system comprises a magnetic coil for generating a magnetic field to actuate an armature and a movable contact and wherein said armature is pivotally supported in a bearing. In order to provide an electromagnetic relay which is particularly uncomplicated and cost effective to fabricate and which exhibits a reduced switching noise, a damping material (122) is disposed at the armature (104) in a region of said bearing (115) for providing a damping (122) of the armature's movement.
