Abstract
A spring biased contact pin assembly includes a barrel member having a barrel wall defining an elongate internal cavity with a lower end and an upper end. The assembly also includes a lower plunger member reciprocally mounted in the internal cavity proximate the lower end of the internal cavity. A spring member is positioned in the internal cavity between the lower plunger member and the upper end of the internal cavity. A high electrical resistance spacer member is positioned in the internal cavity in contact with the lower plunger member and the spring member. Spring force exerted through the spacer member urges the lower plunger member into electrical contact with the barrel wall. A method of transmitting electricity through an electrical contact assembly includes urging a plunger member against the wall of a barrel member in which it is reciprocally mounted with a high electrical resistance member.
