A keyboard includes a first substrate, a second substrate, a keyswitch circuit, a connecting member, and a keyswitch assembly. The first substrate has a first through hole. The second substrate is disposed on the first substrate and has a second through hole. The second through hole is connected to the first through hole and located within an inner edge of the first through hole. The keyswitch circuit is disposed on one of the first substrate and the second substrate. The connecting member is engaged with the second through hole and extended onto a bottom surface of the second substrate facing toward the first substrate. The keyswitch assembly is located on a top surface of the second substrate facing away from the first substrate, connected to the connecting member, and configured to trigger the keyswitch circuit.

A membrane keyboard structure and a conductive method thereof allows a first surrounding portion of a first flexible circuit layer to be deformed to pass through an through hole to be in direct contact and conduction with a second surrounding portion temporarily when it is pressed through the coordination of a first flexible sheet body, first flexible circuit layer configured on the first flexible sheet body, spacer layer positioned on one side of the first flexible sheet body adjacent to the first flexible circuit layer, second flexible sheet body configured on one side of the spacer away from the first flexible circuit layer and second flexible circuit layer configured on one side of the second flexible sheet body adjacent to the spacer layer. Whereby, the present invention can achieve the contact and conduction anywhere to make the use thereof easier and more convenient.

What is presented is a key module (120) for a keyboard. The key module (120) comprises a first wing element (230) and a second wing element (230) for guiding a movement of the key module (120) upon actuation. Each wing element (230) comprises a bar, a first arm and a second arm. The arms extend away from the bar. A mounting portion (232) is formed on the bar. A first bearing portion (234) for bearing the wing element (230) is formed on the first arm. A second bearing portion (234) for bearing the wing element (230) is formed on the second arm. The first wing element (230) and the second wing element (230) are mechanically coupleable to each other. The key module (120) also comprises at least one spring element (240) for providing a reset force upon actuation of the key module (120). The at least one spring element (240) is mountable to the mounting portion (232) of the first wing element (230) and the mounting portion (232) of the second wing element (230). The key module (120) further comprises a support element (250) for supporting the wing elements (230). A plurality of accommodating portions (252) for accommodating the bearing portions (234) of the wing elements (230) are formed in the support element (250).

A keyboard includes a base, a keycap, and a connecting assembly. The keycap is located over the base. The connecting assembly is located between the base and the keycap and includes a first connecting member and a second connecting member connected to each other. Each of the first and second connecting members is connected to the base and the keycap. Two connected members of the base, the keycap, and the first and second connecting members are fixedly connected. When the keycap is pressed toward the base, at least one of the first and second connecting members elastically deforms to store elastic potential energy. When the keycap is released, said at least one of the first and second connecting members elastically recovers to return the keycap to its original position.

An accessory device for an electronic device is described. The accessory device may include a cover section and a keyboard section. The cover section may include a receiving surface that engages the electronic device. The cover section may include electrical contacts designed to electrically couple with contacts on the electronic device. The cover section may include several magnets designed to magnetically couple with magnets within the electronic device. The keyboard section may include a keyboard and one or more channels designed to receive and position the electronic device in a usable configuration with the keyboard. Several magnets may surround each channel, and may magnetically couple with magnets within (and along an edge of) the electronic device. The magnetic circuits formed between the channel magnets and the device magnets may counter, or offset, forces that otherwise remove the electronic device from the channel in an undesired manner.

The invention relates to a system (10) for controlling industrial or all-terrain vehicle functions, which comprises data processing means (20), such as a computer, and a plurality of devices (10a-10g) for controlling industrial or all-terrain vehicle functions. The control devices are arranged in a network with the data processing means (20) according to a master-slave model, and each control device comprises at least one first control member (3a) sensitive to contact and connectors (2), a computing circuit (1) with at least one data processing unit (MC), a memory in which is stored a unique identifier associated with said control device, and at least one first control state visualization member (4a). The data processing means (20) are configured to transmit to each identified control device (10a-10g) a request to obtain a feedback of information from the associated processing unit.

A keyboard device includes a base, a wing-type connecting element and a keycap. The base plate includes a close-type connecting bracket. The wing-type connecting element includes a first frame and a second frame. A connecting shaft of the second frame is received within the close-type connecting bracket. Consequently, the wing-type connecting element is connected with the base plate. While the keycap is depressed, the connecting shaft is only allowed to be rotated and limited within the close-type connecting bracket. Since the swinging range of the wing-type connecting element is reduced, the keyboard device of the present invention is capable of improving the depressing stability of the keycap.
