MEMBER FOR PUSH-BUTTON SWITCH AND METHOD OF MANUFACTURING THE SAME

摘要

A member for a push-button switch manufacturable at low cost and with high yielding and having key top members positioned close to each other through a distance of 1.5 mm or shorter and a method of manufacturing the member for the push-button switch. The member (1) for the push-button switch comprises a plurality of key top members (2) having resin key top cores (21) and thermoplastic films (22) covering the key top cores (21) other than the lower surfaces thereof. The key top members (2) are so formed that an interval between at least one set of adjacent key top members (2) among the key top members (2) is 1.5 mm or shorter. In the key top members (2) adjacent to each other through a distance of 1.5 mm or shorter, the maximum thickness (t0) of the thermoplastic films (22) covering the key top cores (21) comes within the range of 75 to 350 µ, and the ratio (t1/t0) of the minimum thickness (t1) of the thermoplastic films (22) covering the key top cores (21) to the maximum thickness (t0) comes within the range of 0.4 to 0.9.
