Title:
CAPACITANCE-TYPE INPUT SWITCH
Document Type and Number:
WIPO Patent Application WO/2010/090263
Kind Code:
A1
Abstract:
Provided is a capacitance-type input switch which can be appropriately contained in a housing or the like of a device, and can effectively suppress a poor electrical connection which occurs due to a three-dimensional formation.
The capacitance-type input switch is comprised of a rigidity applying layer (1) to be contained in a housing of a device, and a lamination sheet (10), the strength of which is increased when stacked on the rigidity applying layer (1). The rigidity applying layer (1) and the lamination sheet (10) are three-dimensionally formed. The lamination sheet (10) is comprised of a base sheet (11); a conductive pattern layer (12) for forming a capacitor; and an ornamental layer (13) stacked on at least one of the base sheet (11) and the conductive pattern layer (12). A conductive element (30) is brought into contact with the conductive pattern layer (12), so that the conductive pattern layer (12) is electrically connected to an outside electric circuit by the conductive element (30). The conductive element (30) composed of a conductive rubber is used to establish an electrical connection to the outside electric circuit. Accordingly, when the capacitance-type input switch is contained in the housing of an electronic device, there is no possibility that an electric cord may occupy a space in which the switch is contained, and may interrupt the installation of the switch.
