The present invention discloses a portable electronic apparatus, which includes a cover casing, a base casing, a first keyboard and a second keyboard. The base casing is pivoted to the cover casing. The base casing includes a keyboard containing portion and a first connecting portion, and the first connecting portion is disposed on the keyboard containing portion. The first keyboard and the second keyboard are disposed in the keyboard containing portion interchangeably, the first keyboard has a second connecting portion, and the second keyboard has a third connecting portion. When the first keyboard is disposed in the keyboard containing portion, the second connecting portion is electrically connected to the first connecting portion. When the second keyboard is disposed in the keyboard containing portion, the third connecting portion is electrically connected to the first connecting portion.

Example implementations relate to modular keyboards. In an example, a modular keyboard can include a keyboard module including keys, where the keyboard module includes a plurality of locking mechanisms, and a lattice removably coupled by the plurality of locking mechanisms to the keyboard module, where the lattice comprises a keyboard overlay.

Apparatus, system, and method for ganging a plurality of wall mounted control devices, such as keypads. Particularly, an assembly of ganged control devices is provided comprising a pair of adjacently positioned control devices each adapted to control at least one function of at least one associated load. Each control device comprises a housing assembly and at least one button attached to the housing assembly. The housing assembly comprises a pair of oppositely disposed side surfaces each comprising a pair of vertically aligned recesses. Each recess comprises a tapered inner side wall. The assembly further comprises an alignment plate comprising a vertical wall adapted to be positioned in between the pair of control devices and a pair of vertically aligned tabs traversely extending from oppositely disposed side surfaces of the vertical wall. Each tab comprises a tapered outer side wall. The tabs are sized, shaped, and positioned to be inserted into the recesses such that the tapered outer side walls of the tabs form a friction fit with the tapered inner side walls of the recesses to removably attach and align the pair of control devices.

Systems, apparatuses, and methods for mounting an object such as a keyboard within a vehicle are disclosed. One mounting system includes a keyboard and a mounting apparatus. The keyboard includes at least one aperture. The mounting apparatus includes a base, a slide plate, a latch, and a locking mechanism. The slide plate is coupled to the base and is slidable in a predetermined direction relative to the base. The latch is movable between an engaged position that prevents the slide plate from sliding relative to the base and a disengaged position that does not prevent the slide plate from sliding relative to the base. The locking mechanism is movable between a locked position in which the locking mechanism engages the at least one aperture to lock the keyboard to the slide plate and an unlocked position in which the locking mechanism does not engage the at least one aperture.

Disclosed are a rocker device and a controller. The rocker device includes a mounting base and a rocker assembly, the mounting base is provided with a first accommodating cavity with an opening, the mounting base is configured to connect with the controller, the rocker assembly is provided in the first accommodating cavity and snapped with the mounting base, the rocker assembly is configured to electrically connect with the controller to achieve multi-directional control.

The invention relates to a user input unit comprising a housing configured to be attached to a base of a user input device, such as a keyboard. The input unit also has a first movable element coupled to the housing, the first movable element being movable along a first direction and user operable second movable element coupled to the housing, the second movable element being movable along a second direction, the second direction being different from the first direction. Further a transmission configured to transfer movement of the second movable element along the second direction into movement of the first movable element along the first direction is provided. The invention also relates to a user input device, such as a keyboard, comprising a base, such a user input unit, and a sensor configured to sense a movement or a position of the first movable element along the first direction.
