A method of producing a device comprises at least one displaceable operating member, wherein a foil (2) is placed into a mould and at least one polymer is injected into the mould 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 mould, after which said polymer is injected into the mould 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 mould, the support element (6) and the flexible part of the foil (2) are mutually disconnected at a location of said reduced adhesion force.
