Abstract
A novel method of producing a contact device for a switch is disclosed. According to the present invention, a powdered contact alloy material is pressed with a substrate on which is placed the contact material. The resulting molded article is sintered for bonding said contact alloy material to said substrate. The resulting sintered product is machined to have the shape of a contact and ultimately an electrode bar is attached by brazing to said substrate.
