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.
