Abstract
This article describes the performance of electrodeposited palladium on a typical telephone two-motion selector plug and socket employing contact forces in the range 100 to 300 grammes. The conclusions are based on environmental tests and electrical measurements which indicate that palladium forms a reliable contact finish in this application.This publication has 3 references indexed in Scilit:
