Abstract
Abstract Contacts of electrically conductive elastomers, integrally fixed to conductors by bonding or molding in place, are situated to contact, with little resistance, mating electrical conductors and elastically deform under the contacting forces to seal the mated conductor surface thereby inhibiting corrosion and maintaining electrical contact.
