ABSTRACT:
A low ampere mechanical switch has a contact design creating a line of contact between the moveable and stationary contacts. The stationary contacts are stainless steel and the moveable contact is Inconel.TM.. Both contacts have a thin plating of gold alloy to provide for good mechanical strength at high temperature with a natural lubricating ability. The contact physical design provides good wiping action and mechanical contact while preventing troughing.
