Welding method and thermostat produced

摘要

A method of welding electrical contacts onto conductive bodies including engaging a surface of the contact with the conductive body and passing a welding current through a pair of spaced surface areas of the contact to provide weld action and wherein a rib portion between the pair of spaced areas retains unoxidized metal thereon to improve electrical contact properties of any article made and utilizing the contact and particularly the ribbed area thereof for make and break engagement with other members of an electric circuit. A new control article is also provided wherein a contact therein has a raised center rib thereon for contacting an associated means for make and break circuit action, which contact is made from silver or silver alloy and has uncontaminated silver on the surface of the rib or center area of the contact.
