Abstract
A relay (30) has one or both current carrying relay contacts (12, 14) made of a soft, deformable, readily fusible metal, preferably indium, lead, cadmium, bismuth, or tin. When the relay (30) closes, the contacts (12, 14) deform or fuse together, ensuring good electrical conductance and eliminating chatter and accidental opening. The relay (30) is particularly useful in a bypass circuit (54) for a spacecraft battery system (50).
