ABSTRACT:
To prevent the contacts of an electrical switch bouncing when the switch is operated, with the attendant arcing and contact erosion, spring mass mechanisms are added adjacent the spring arms and contacts to engage such spring arms and contacts and transfer the vibrational energy to such spring mass mechanisms and permit the spring arms and contacts to operate without any contact bounce. An energy absorber can be used alternatively to absorb the vibrational energy. A combination of spring mass mechanism for one spring arm/contact assembly and an absorber for the second spring arm/contact assembly can be employed.
