Abstract

A membrane switch includes an upper electrode sheet that includes an upper electrode, a lower electrode sheet that includes a lower electrode facing the upper electrode, and an adhesive layer that joins the upper electrode sheet to the lower electrode sheet; and the upper and lower electrodes come into contact with each other due to a pressing force, which is applied to at least one of the upper electrode sheet and the lower electrode sheet, and conduct electricity. The upper electrode sheet includes: an upper base on which the upper electrode is formed; and an upper insulating layer that is provided between the upper base and the lower electrode sheet, includes a first opening at a position corresponding to the upper electrode, and is joined to the lower electrode sheet by the adhesive layer. The upper insulating layer is formed on the upper base.

Description

technical field [0001] The present invention relates to switches and methods of manufacturing the same. [0002] For the designated countries that approve the introduction by reference of documents, the content described in Japanese Patent Application No. 2015-248390 filed in Japan on December 21, 2015 is incorporated into this specification by reference and forms a part of this specification. Background technique [0003] Known have following switch, this switch is provided with: the electrode sheet of upper and lower sides; Spacer, it is arranged between the electrode sheet of up and down and forms the desired interval between the electrode sheet of up and down, and the electrode sheet of up and down is separated from spacer. objects are bonded via an adhesive (for example, refer to Patent Document 1). In the switch described in Patent Document 1, an opening for allowing upper and lower electrodes to come into contact is formed in the spacer, and an adhesive is provided a...
