Abstract

Deliberate contamination of palladium surfaces of electrical contacts with mercury prevents the formation of polymer or other insulating films which are the cause of increased electrical resistance. This contamination is achieved by immersing the contacts in a solution containing mercury chloride in which free mercury is precipitated to form the desired amalgam at the surfaces of the contacts.
