Method of producing a device comprising at least one displaceable operating member as well as such a device

摘要

A method of producing a device comprises at least one displaceable operating member, wherein a foil (2) is placed into a mold and at least one polymer is injected into the mold to form a housing wall (3) adhering to the foil (2). The displaceable operating member comprises at least a flexible part of the foil (2) extending over a hole (5) in the housing wall (3). The foil is inserted into the mold, after which said polymer is injected into the mold to form the housing wall (3) with the hole and to form a support element (6) located in the hole (5). A gap (7) is provided between the support element (6) and the housing wall (3). The support element (6) is, at least at an outer area (9) near the gap (7), adhered to the foil (2) with a reduced adhesion force compared to an adhesion force between the housing wall (3) and the foil (2). After removing the device from the mold, the support element (6) and the flexible part of the foil (2) are mutually disconnected at a location of said reduced adhesion force.

主权项

1. A device including a displaceable operating member, said device comprising:
a housing wall having a hole defined therein; a foil adhered to the housing wall and having a flexible part extending flatly across said hole; and a support element movably disposed in the hole beneath the flexible part of the foil, said support element having a central area that is non-detachably adhered by a semi-adhesive material to a corresponding central area of the flexible part of the foil and having an outer area that is releasably adhered to a corresponding outer area of the flexible part of the foil surrounding the central area of said of said flexible part of the foil;said flexible part of the foil and said support element collectively forming said displaceable operating member.
