What is presented is a key module for a keyboard. The key module comprises a key tappet. The key module also comprises a module housing. The module housing is formed to movably accommodate the key tappet, in order to enable a translational actuation movement of the key tappet between a rest position and in an actuated position relative to the module housing. The key module further comprises a trigger element for triggering an actuation signal of the key module in response to the actuation movement. The trigger element is attached to the key tappet. The trigger element is a contactor for electrically shorting contact pads of a circuit substrate of the keyboard. The trigger element comprises more than two elastically deformable contact fingers for contacting the contact pads after different pre-travel paths in the course of the actuation movement.

A button structure comprises a base layer, a supporting structure arranged on the base layer, an elastic film layer, the elastic film layer covering the support structure and connected to the support structure, the support structure and the elastic film layer defining a cavity above the base layer, a first upper electrode arranged on the lower surface of the elastic film layer and located in the cavity, a first lower electrode, arranged on the base layer and located in the cavity, and a first variable resistance elastic body between the first upper and first lower electrodes, either arranged on the lower surface of the first upper electrode or arranged on the upper surface of the first lower electrode. When the elastic film layer is elastically deformed in the direction of the base layer, the first variable resistance elastic body connects the first upper electrode with the first lower electrode so as to generate a first signal related to the elastic deformation of the first variable resistance elastic body.

An electronic push button for a motor vehicle door handle, including an activation pattern supported by a membrane that is flexible in the direction of an electric switch carried by a printed circuit board, the activation pattern defining an activation surface that is pressed by an operator's finger in order to push the activation pattern in the direction of the electric switch. The activation pattern is made up of a set of studs that extend parallel to one another away from the electric switch, with the majority of the studs being spaced apart from one another, the set of studs discontinuously delimiting an outer contour of the activation surface of the electronic push button.

A peripheral device for a computing system comprises an electrical switch and a user depressible button. An electrostatic brake is attached to the user depressible button and controls a force profile of the keystroke of the user depressible button. The button is coupled to and is configured to actuate the electrical switch at the end of the keystroke. A movable electrode is coupled to the depressible button and a stationary electrode is positioned parallel to and proximate the movable electrode. A dielectric material is positioned between the movable electrode and the stationary electrode forming an electrostatic brake. An electrical circuit is coupled to the first and the second electrodes and is configured to apply a voltage potential between the first and the second electrodes to apply a resistive force to the depressible button.
