A key structure includes a movable element, an elastic element, a light-emitting element and a pressure sensing element. The pressure sensing element is arranged between the elastic element and the light-emitting element. The elastic element is disposed on the movable element. The light-emitting element emits a light beam. The light beam is transmitted through the pressure sensing element and projected to the movable element to illuminate the key structure. While the key structure is depressed, the elastic element is pushed by the movable element. The pressure sensing element is pushed by the elastic element according to different magnitudes of the depressing force. Consequently, the key structure generates different pressure sensing signals.

An illuminated keyswitch structure with an illuminating module includes a base plate, a drive circuit board under the base plate, a spacer between the drive circuit board and the base plate, and a light-emitting part on the circuit board. The spacer has a through hole communicating with an opening of the base plate in a vertical direction. The light-emitting part is located in the through hole, and falls within a projection of the opening in the vertical direction. The light-emitting part has a top surface that is lower than or equal to a bottom surface of the base plate in the vertical direction. The structure of the illuminated keyswitch structure around the light-emitting part can keep flat by the spacer. The spacer can prevent the light-emitting part from structurally entering the opening, avoiding structural interference between the light-emitting part and other components above the base plate.

The invention relates to an actuating element comprising corona illumination, having a handle (1), which can be moved linearly in a stationary housing (3) from a raised non-actuating position to a lowered actuating position by manually impacting on its horizontal actuating surface (2). Said actuating element further comprises a circumferential border (5) of the handle (1), which protrudes into the direction facing away from the actuating surface (2) and forms an annular gap (7) between the end thereof facing away from the actuating area (2) and a housing wall (6), which annular gap (7) leads radially outward from the housing interior (4) below the actuating area (2) to the housing exterior surrounding the handle in order to cause a linear movement of the handle (1). Said actuating element further comprises a light source (12) arranged in the housing interior (4), the light whereof can be guided via an annular optical waveguide (11) corresponding to the border (5) of the handle (1) to the annular gap (7) and through same radially outward to the outside of the housing wall (6). Said actuating element further comprises electrical and/or electronic components arranged in the housing interior (4). The annular optical waveguide (11) has an annular wall which extends in the direction of the linear movement of the handle (1) and by means of which the housing interior (4) comprising the light source (12) and the electrical and/or electronic components is separated from the end area of the annular gap (7) facing the housing interior (4), wherein a channel (18) is formed between the annular wall and the housing (3) surrounding the annular wall, which channel (18) opens outward at its bottom end and wherein the optical waveguide (11) and the annular wall are configured in one piece (30).
