Remote control devices may control electrical loads and/or load control devices of a load control system without accessing electrical wiring. The remote control device may be mounted over a mechanical switch that is installed in a wallbox. The remote control device may include a base, a battery, a battery holder, and a control unit. The base may be configured to attach the remote control device to the mechanical switch. The control unit may be configured to be removably attached to the base. The battery holder may be configured to retain the battery therein. The battery holder may be configured to be installed within the void defined by the housing. The battery holder may be operable between a first position in a lower portion of the void and a second position in an upper portion of the void.

A user-upgradeable modular component keyboard for an information handling system comprising a replaceable keyboard layout structure having a plurality of keys and operatively coupled to a replaceable keyboard power and connectivity module via a key switch data connector and a releasable fastener. The replaceable keyboard power and connectivity module housing a keyboard controller for communicating detected keystrokes to the information handling system and a power source for powering the keyboard controller, the replaceable keyboard power and connectivity module having a key switch data connector first side to operatively couple to a key switch data connector second side on the replaceable keyboard layout structure for transfer of data and power, and the replaceable keyboard power and connectivity module having a releasable fastener first side for operative coupling to a releasable fastener second side on the replaceable keyboard layout structure.

Power control devices are provided with electrically isolated outputs. One exemplary power control device comprises control electronics configured to: (i) receive a power signal from a DC power source, wherein the control electronics comprise an input ground for the DC power source; and (ii) provide multiple outputs, wherein the multiple outputs is supplied power from the DC power source; wherein the multiple outputs comprise at least one output that is electrically isolated from at least one other output of the multiple outputs that each provide power to one or more of a plurality of loads, wherein the electrical isolation is based on the at least one output having a first output ground that is isolated from a second output ground of the at least one other output, and wherein the input ground, the first output ground, and the second output ground are electrically isolated from each other.

A light switch includes an outer housing formed with a plurality of intersecting walls to define a recess and including a first ferromagnetic material. The outer housing is configured to be coupled with an external structure by a plurality of mounting brackets integrally formed as part of the outer housing and extending outwardly therefrom. The light switch also includes an inner housing. The inter housing includes a user controllable switch mechanism and a second ferromagnetic material. At least one of the first ferromagnetic material and the second ferromagnetic material comprises a permanent magnet, and the inner housing is sized to be received and removably maintained in the recess formed in the outer housing by magnetic attraction between the first ferromagnetic material and the second ferromagnetic material.

An operation device driven by an internal battery includes: a casing; an operation element; a mechanical switch; a pressing part; and a support part. The operation element is located on a plane continuing from a front surface of the casing. The mechanical switch is disposed in the casing such that a distance between the mechanical switch and the operation element is fixed. The mechanical switch has a flexible region located to oppose to a rear surface of the casing. The pressing part is located between the mechanical switch and an attachment surface, and presses the flexible region from a side opposite from the operation element. The support part supports the casing such that a distance between the operation element and the attachment surface is changeable.

An electrical device such as, for example, a battery-powered electrical switch is disclosed. The battery-powered wireless switch includes one or more mechanisms arranged and configured to provide simplified access for servicing (e.g., replacing) the batteries located within the wireless switch. In one embodiment, the wireless switch is arranged and configured so that the batteries may be accessed by reconfiguring the wireless switch from a first closed position to a second opened position to access the batteries. Thus arranged, removal of the wireless switch from a wall-box or a surface of a wall is not required, the user may only need to remove the wall-plate in order to reconfigure the wireless switch. In one embodiment, at least a portion of the wireless switch is pivoted from the first position to the second position to provide access to the batteries.

An information handling system keyboard liquid crystal display (LCD) presents visual images illuminated by light emitting diodes (LEDs) at an underside of the LCD within the keyboard, such as to present function keys or a number pad. A photovoltaic panel placed over the LCD recycles illumination passing through the LCD and also absorbs ambient light to convert the light to a current that is applied to charge a battery of the keyboard.
