The dual-switch housing is configured to secure two separate switches on a rail interface system and includes an actuator that allows an end-user to activate both switches individually or simultaneously. An example dual-switch housing comprises: a housing including rail clamp portions for removably mounting the dual-switch housing to the rail interface system; and an actuator configured to actuate the first and second switches individually or simultaneously. The actuator comprises a first actuation button configured to actuate only the first switch, a second actuation button configured to actuate both the first switch and the second switch, and a third actuation button configured to actuate only the second switch.

A lighting keyboard includes a plurality of keys and a backlight module. Each of the keys has a keycap. The backlight module is located below the keys. The backlight module includes a plurality of light emitting units and a light guide plate. Three of the light emitting units are arranged in a triangle to form a light emitting area. The light emitting area overlaps with at least two keycaps. The light guide plate is provided with two relatively sparser microstructure regions and at least one relatively denser microstructure region on a connection line of at least two of the three light emitting units. The two relatively sparser microstructure regions are respectively close to the at least two light emitting units. The at least one relatively denser microstructure region is located between the two relatively sparser microstructure regions.

A switch unit includes a sliding member which is slidable by pressing operation of the operating member, and a supporting member that supports the sliding member. An electrical contact is opened and closed in accordance with sliding movement of the sliding member. The sliding member includes a pedestal, a first projection provided on a pressing operation side and capable of attaching the operating member, and a column provided on a side opposite to the pressing operation side from the pedestal along the sliding direction. The supporting member includes a plate and a first guide provided from the plate to the pressing operation side along the sliding direction. The pedestal has a first through hole through which the first guide passes, and the first guide has a second through hole into which the column is inserted.

A keyboard is disclosed for allowing the manipulation of the position of its key rows with respect to its base so that a key layout may be customized to a user's preference. The keyboard includes a base, at least one key row, and at least one key base. The base includes a tray formed therein. The at least one key row is disposed within the tray and includes a plurality of keys linearly arranged along a first direction. The at least one key base connects the at least one key row to the base and is configured to move the at least one key row along the first direction with respect to the base.

An actuator switch includes a first switch member is movable from an inactivated position to a first toggle position in a first direction and a second toggle position in a second direction and a third toggle position in a third direction transverse to the first and second directions and a fourth toggle position in a fourth direction opposite the third direction. A first switch member is movable from an inactivated position to a first position in an upward direction and a second position in a downward direction. A keypad includes a first group of two electrical contacts each associated with the second switch member and a second group of four electrical contacts each of which is associated with the first switch member.

A keyboard system comprises a housing and a key structure having a key body and key cap. The key body includes a transceiver circuit. The key cap includes a key cap transceiver and a memory structure storing a key cap ID data and/or a key function data corresponding to a key function. The transceiver circuit can poll the key cap memory via the key cap transceiver and retrieve the key cap ID data and/or the key function data. The keyboard system can determine a mapping of a location of the key cap on the keyboard by polling it and can generate and transmit a control signal to a host computing device communicatively coupled to the keyboard system based to the key cap ID and/or the key function data.
