Abstract
Abstract A panel switch for use in electronic apparatus and a method for making same, the panel switch employing a diaphragm whereby the operator turns on the switch with a feeling of security. To locate a diaphragm, a sheet having an adhesive layer on one side is used instead of a conventional spacer, and the diaphragm is secured to an insulated substrate with the sheet. The non-use of the spacer saves cost and labor, thereby producing panel switches more economically.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
130 words
A process for making a panel switch, the process comprising the steps of: preparing a strip of tape having a width, a strip direction, and an adhesive layer on one side, a central part of the adhesive layer being covered with a strip of an adhesion-prohibiting layer having a width smaller than that of the adhesive layer and a strip direction generally parallel with respect to that of the tape; preparing a strip of hoop-like diaphragms, each of the diaphragms having a central aperture; joining the tape to the strip of hoop-like diaphragms so that the central apertures are covered with the adhesion-prohibiting layer; cutting the joined tape and the strip of hoop-like diaphragms into unit diaphragms; and securing each unit diaphragm to a substrate at respective contact points thereon.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
107 words
A process for making a panel switch, the process comprising the steps of: preparing a strip of hoop-like diaphragms, each of the diaphragms having a central aperture; preparing a strip of tape having a width, a strip direction, and an adhesive layer on one side, wherein the tape has no adhesive at spots corresponding to the central apertures of the diaphragms; joining the tape to the strip of hoop-like diaphragms so that the central apertures are not covered with the adhesive; cutting the joined tape and the strip of hoop-like diaphragms into unit diaphragms; and securing each unit diaphragm to a substrate at respective contact points thereon.
