The present disclosure relates to a system of assemblies for remotely actuating a tap box to a continuous access busway. The system includes a tap box having a male component with electric contacts positionable between an engaged position and a disengaged position with a continuous access busway. A remote actuator interface positioned along the tap box for being selectively attached to a remote actuator device for manipulating the male component between the engaged position and the disengaged position. The remote actuator device may be a powered actuator device or an elongated control rod wherein the powered actuator device and elongated control rod may be selectively coupled to the remote actuator interface to manipulate the male component between the engaged position and the disengaged position relative to the continuous access busway from a safe distance to reduce the event of injury due to arch flashing or electrocution.

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.

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.

A power plate pedal board for musical instrument electronics is provided. An exemplary battery powered pedal board structure comprises: at least one battery; and control electronics, wherein the at least one battery and control electronics are housed within the battery powered pedal board structure, wherein the battery powered pedal board structure is configured to mount a plurality of musical effects pedals and to support a load applied to the plate assembly by one or more musician, and wherein the control electronics are configured to provide a plurality of outputs from one of the at least one battery, wherein the plurality of outputs comprise one or more of: (i) one or more outputs that are electrically isolated from each other and provide power to the plurality of musical effects pedals, and (ii) one or more outputs that are not electrically isolated from each other and provide power to one or more of the plurality of musical effects pedals.
