The invention relates to a peripheral (1) including at least one transparent key (2), actuable under the effect of pressure and engaged in an opening (11) arranged on a first face (10a) of a case (10), the peripheral (1) including a system (13) for controlling and detecting a pressure exerted on the key (2), and at least one screen (4) allowing symbols (3) to be displayed through each key (2) via respectively a display path (5), the control and detection system (13) including a flexible membrane (14) ensuring an actuating force and a pressure feedback effect and including at least one orifice (17), each orifice delimiting a display path (5) for a key (2), and each orifice (17) being delimited by a border (17a) cooperating with a key (2).

A key module includes an actuation element with a cam nose and a contactor unit with a contact nose movable in the direction of the movement axis and transverse to the direction of the movement axis. Also, a contact element is formed and arranged for establishing electric contact with the contact nose. Moreover, the housing element accommodates the contact element, the contactor unit and the actuation element, wherein the actuation element and/or the cam nose includes a constructive element formed to deflect the contact nose from a rest position adjacent to the contact element in the direction along and/or transverse to the movement axis upon a defined movement of the actuation element, then abruptly release it so that the movable contact nose returns to the rest position and strikes the contact element and/or the housing element. Electric contact with the contact element is established and acoustic noise is produced.

The present utility model discloses a keyboard. The keyboard comprises keys, a fixing frame, long flexible strips, a key locking plate, a flexible sheet, a PCB board, a flexible base, and a bottom cap. The key locking plate is mounted on the upper surface of the flexible sheet. The flexible sheet is mounted on the upper surface of the PCB board. The PCB board is mounted on the flexible base. The flexible base is mounted on the bottom cap. The key locking plate, the flexible sheet, the PCB board and the flexible base fixed in the housing. The long flexible strips are mounted on all sides of the key locking plate and in the fixing frame.

A mouse device includes a casing, a circuit board and two button modules. The circuit board is disposed within the casing. Each button module includes an electronic switch, a button lid, a first protrusion post, a second protrusion post and a buffering structure. The electronic switch is disposed within the casing. An end of the button lid is connected with the casing. The first protrusion post and the second protrusion post are disposed on the bottom surface of the button lid. The buffering structure is disposed on the casing and aligned with the second protrusion post. The second protrusion post is inserted into a buffering hole of the buffering structure. While the button lid is depressed or the pressing force is released, the buffering structure is contacted or not contacted with the second protrusion post along a first lateral direction and/or a second lateral direction.

What is presented is a key module (100) comprising an actuation element (105) comprising a cam nose (135), wherein the actuation element (105) is supported to be movable along a movement axis (200) in a housing element (130, 110). Furthermore, the key module (100) comprises a contactor unit (115) with a contact nose (140) movable in the direction of the movement axis (200) and transverse to the direction of the movement axis (200). Also, the key module (100) comprises a contact element (120) formed and arranged for establishing electric contact with the contact nose (140). Moreover, the key module (100) comprises the housing element (130, 110) for accommodating the contact element (120), the contactor unit (115) and the actuation element (105), wherein the actuation element (105) and/or the cam nose (135) comprises at least one constructive element (400) formed to deflect the contact nose (140) from a rest position adjacent to the contact element (120) in the direction along and/or transverse to the movement axis (200) upon a defined movement of the actuation element (105), then abruptly release it so that the movable contact nose (140) returns to the rest position and strikes the contact element (120) and/or the housing element (130, 110), wherein electric contact with the contact element (120) is established and acoustic noise is produced.

A keyboard device includes a membrane circuit board and a key structure over the membrane circuit board. The key structure includes a keycap, a plunger structure, a key pedestal and an elastic element. The plunger structure is arranged between the keycap and the elastic element. At least a portion of the keycap is disposed within a pedestal dust-storage chamber of the key pedestal. At least a portion of the plunger structure is disposed within a guiding chamber of the key pedestal. Due to the relative location between the keycap, the plunger structure and the key pedestal, the path of the dust to enter the guiding chamber is extended or blocked. Consequently, the dust-proof efficacy is enhanced.

A pushbutton assembly comprises a base, a pushbutton which is displaceable in a push direction relative to the base from an unactuated rest position into an actuated position and vice versa, and a return device which biases the pushbutton towards the rest position. Further, a self-centering device is provided which comprises a button part and a base part, the button part and the base part of the self-centering device cooperating in the rest position of the pushbutton so as to position the pushbutton in a centered position with respect to the base.
