Abstract
The switch housing for capacitive switches has an outer contact surface and flat electrode structures which are arranged on the inside and in a position opposite the contact surface and which are placed by two-component injection molding in recessed regions of the housing body injected from a first, electrically non-conductive plastic component by means of a second, electrically conductive plastic component. Preferably, both plastic components are a polycarbonate, the second plastic component containing carbon fibers.
Claims18
A method of producing a switch housing for capacitive switches having a contact surface by two-component injection molding, a housing body being injected using a first, electrically insulating plastic component, the housing body having recessed regions on the inside in a position opposite the contact surface, and a second, electrically conductive plastic component containing the same base material as the first plastic component being injected into the recessed regions.
A switch housing for capacitive switches, having an outer contact surface and flat electrode structures which are arranged on the inside in a position opposite the contact surface and which are placed by two-component injection molding in recessed regions of the housing body injected from a first electrically non-conductive plastic component by means of a second, electrically conductive plastic component, and wherein the flat electrode structures are configured with integrally formed contact tags which are guided to a contacting block formed integrally on the inside of the housing body
