Button Contacts
Clad button contacts are produced from hot bonded bimetal or trimetal overlays using one of two methods.

(1) A clad overlay strip is processed in progressive dies to produce the finished button contact, or (2) contact blanks are subsequently formed to their final sizes in a separate operation. Because ECL commonly utilizes both techniques to produce buttons, our customers can be assured of sound advice on the design of this style of contact. Fine silver, silver/copper alloys, silver nickel and silver metal oxide materials can all be supplied in the clad metal contact form. Button contacts are also produced by the "melt & coin" method. In this method, fine silver and some silver alloys can be processed so that they adhere to the contact substrate. Subsequently, they are coined to final dimensions to provide a very simple and economical button contact.
