Abstract
Abstract An electrical connection is formed by coating two conductors with a metal capable of forming an amalgam with mercury, forming an amalgam by immersing the coated conductors in a mercury bath, withdrawing them thereby leaving a small meniscus of excess mercury on each amalgam, and placing the meniscuses of mercury in contact with each other.

Claim 1
Independent Claim
107 words
Method for obtaining non-permanent electrical connections at ambient temperatures comprising coating each of the conducting members to be connected together with a thin layer of a metal capable of constituting an amalgam with mercury, forming, on each of said members, an amalgam topped with a thin film of mercury in the form of a meniscus with a small curvature by placing each of said members in contact with a surplus of mercury with respect to the quantity that is stoichiometrically necessary for the constitution of the amalgam, and juxtaposing the mercury meniscuses formed, respectively, on the members to be connected adjacent each other without applying pressure therebetween.
