ABSTRACT:
In one embodiment, a method for reducing signal noise in a relay having pass-through and attenuator circuits which are alternately closed by operation of an armature assembly of the relay is disclosed. In accordance with the method, the armature assembly is provided with a grounding portion. The grounding portion of the armature assembly is oriented to make contact with the pass-through circuit when the attenuator circuit is closed, but not when the pass-through circuit is closed.
