Abstract
A cordless electrical appliance includes a male pin connector which engages vertically with a female socket connector mounted in a base for the appliance. The contacts are arranged such that one of the line or neutral connections makes last and breaks first. This connection includes a silver, copper backed contact mounted on a leaf spring with a corresponding male pin being made of copper and having a thin silver plating at least in a region of contact with the copper backed contact.
