'ELECTROMAGNETIC RELAY HAVING A DAMPING LAYER COATING FREE EXTERNAL SURFACES'

摘要

The invention relates to an electromagnetic relay (10) comprising: - a base (12) enclosing an electromagnet (18); - A blade (26) having a first arm (28) fixed on the base (12), and a second arm (30) movable, a section (31) resiliently flexible hinge; - An armature (40) which is fixed on an inner face of the arm (30) movable vis-à-vis the electromagnet (18) and which is articulated on the base (12); the relay (10) having external faces (32, 44, 46, 48, 50) which are turned away from the electromagnet (18), and which have free surfaces, characterized in that comprises at least one viscoelastic material damping layer (52A, 52B) which covers at least a portion of the free outer surfaces of the relay (10), the same damping layer (52A, 52B) covering only the outer free surfaces of the relay fixed elements relative to each other.
