Abstract
A portable electronic user device, in the form of an electronic key, having an inherently rigid button for activation by a user. The portable electronic user device further has a flexibly deformable membrane including a first side having at least one support section on which the at least one button is supported via the plunger, and an actuating section, separate from the at least one support section, for receiving and forwarding an actuation of the button to an electrical switch element. There is a rigid frame which bears the membrane on a second side opposite the first side, wherein, in the assembled state, having the membrane in the region of the at least one support section, the frame has at least one breakout, via which the membrane is moveable by the plunger upon activating the at least one button and, in dependence on the size and/or the shape of the breakout, provides a force for resetting the button. As a result of the separation of the generating of the reset force on the support sections movable by the first breakouts and the switch function in the region of the activation section, there is great freedom in the design of the portable electronic user device, wherein reliab…
