Claims

[Claims for Utility Model Registration] 1. An upper electrode sheet and a lower electrode sheet each having an electrode contact on one side of a transparent insulating plastic film, and a spacer having a space between which the electrode contact is formed within the space. In an illuminated membrane switch in which the lower electrode sheet is stacked so as to face each other so as to be able to be freely approached and separated, and a light emitting element is provided below the electrode contact of the lower electrode sheet, a light-transmitting gap is provided in the electrode contact area to penetrate both electrode contacts. 1. A light-emitting membrane switch characterized in that a reflecting plate is formed of conductive paste and has a reflective plate around a light-emitting element that reflects light from the light-emitting element toward the electrode. 2. Each electrode contact is formed by a plurality of connected thin wires, and when the upper electrode sheet and the lower electrode sheet are combined, the thin wire forming the electrode contact on the upper electrode sheet and the electrode contact on the lower electrode sheet are 2. The light-emitting membrane switch according to claim 1, wherein the thin wires are arranged so as to intersect with each other.
