Abstract
A multicontact switch for use in a keyboard is manufactured from a plurality of metallic strips and a printed circuit board. The strips are passed through rollers that form arched portions in the strips, and the arched portions are then aligned with contact areas on the printed circuit board. After this alignment the strips are spot welded to the printed circuit board while they are held in place by clamps. After one board has been welded to the strips it is moved from the welding station and another group of arched portions in the strips is aligned with another board. Following this alignment the strips are sheared between the two boards, thereby producing a completed multicontact switch structure.
