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: 2
Claim 1
Independent Claim
83 words
A process for making a panel switch, the process comprising the steps of joining a tape having an adhesive layer on one side to a strip of resilient hoop-like diaphragms, cutting the strip of diaphragms into units such that each of the diaphagm units is individually covered by a separate adhesive sheet, and securing each diaphragm unit to an insulated substrate having electrical contact points, said diaphragm units serving as actuators to make electrical contact with said electrical contact points of said substrate.
