Abstract
Abstract A process for selectively manufacturing vertical or horizontal type switch devices using a common form for substantially all parts or components, and products manufactured by the same process. The process comprises subjecting a metallic strip to stamping-out to leave predetermined patterns, each pattern consisting of a set of fixed contact elements, and two groups of terminals extending from the fixed contact elements and perpendicular to each other, and passageways between adjacent terminals in part; cutting some selected sites from the passageways so that one desired group of terminals in accordance with horizontal or vertical type may remain connected to the fixed contact elements before or after the molding with an insulating synthetic resin so that each resulting pattern may be inserted in the mold formed thereby; and making assembly of the thus-obtained mold-with-terminal-pattern and other parts and components.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
245 words
A process of manufacturing horizontal and vertical type switch devices comprising the steps of: (a) stamping a metallic, electrically conductive strip so as to form predetermined patterns therein, said patterns defining a set of common fixed contact elements, a first group of terminals extending from the fixed contact elements in a first direction, and a second group of terminals extending in a second direction perpendicular to the first direction, said second group of terminals being electrically connected to respective ones of said first group of terminals and said first group of terminals being electrically connected to respective ones of said fixed common contacts through interconnecting sites; (b) cutting selected ones of said interconnecting sites so that one desired group of terminals remains electrically connected to the respective ones of said fixed contact elements; (c) molding said strip in an insulating synthetic resin so that said two group of terminals have their respective ends projecting from respective sides thereof in said first and second directions; (d) cutting the projecting ends of the group of terminals not electrically connected to said fixed contact elements and separating the molded unit of said fixed contact elements and remaining terminals from said metallic strip; and (e) installing a slide carrying a movable contact element and said molded unit in a frame such that said slide and movable contact element are positioned for operative sliding contact movement relative to said fixed contact elements so as to form the desired switch device.
