Abstract
In a method of manufacturing a diaphragm with a contact, contact stocks each forming a movable contact on a stock formed out of a strip-shaped thin metal sheet material, or a rolled material are bonded at predetermined intervals to the stock by resistance welding, for example to form a diaphragm stock with a contact. Next, the stock of a diaphragm with a contact is subjected to continuous blanking with a predetermined diameter from each movable contact as center to produce a diaphragm with a contact.
Claims16
