An example of a button device includes a keytop, a spacer and a substrate. At least a part of the keytop is light-transmissive. The spacer is provided below the keytop and at least a part of the spacer is light-transmissive. The substrate is provided below the spacer and has a light-emitting section and a detection section on an upper surface. A lower surface of a central portion of the keytop is located on an upper side relative to a lower surface of an outer edge portion around the central portion. The spacer includes a protruding portion protruding in a downward direction. The protruding portion presses the detection section in response to movement of the spacer in the downward direction due to the keytop being pressed.

The invention relates to a device for detecting a key press of a keyboard, comprising a key module, a circuit substrate, a planar coil arranged on or in the circuit substrate, and at least one damping element, wherein the at least one damping element for damping the planar coil is movably arranged in the key module between a rest position and an actuation position, wherein the damping element executes a first actuating movement during the movement in the direction of the actuation position and executes a second actuating movement) during the movement towards the rest position, and wherein the device (10) outputs at least one electrical signal when carrying out the first actuating movement and/or the second actuating movement.

The invention also relates to a keyboard comprising one or more such devices and to a method for detecting a key press of a key module with such a device.
