ABSTRACT:
A method for manufacturing multiple push-button and conductive members for dual-in-line package (DIP) switches includes the steps of: integrally forming a multiple push-button member and a conductive member in respective molds; superimposingly combining the push-button member and the conductive member together for being pressed as a single solid unit; and cutting each combined solid unit into a plurality of push-button units. Each of the integrally formed push-button members includes an enclosed frame, a plurality of partitioning ribs symmetrically spaced in the enclosed frame, and a predetermined quantity of push-button bodies respectively provided in rows between the partitioning ribs; and each conductive member includes a pair of supporting bands formed in parallel in conjunction with the enclosed frame, and a predetermined quantity of conductive pieces integrally connected in rows between the supporting bands. Thus, after the two members are combined into a single piece, all the push-button bodies can be simultaneously cut into units in an integrated operation without any burs left on them.
