A control device may be configured to control one or more electrical loads in a load control system. The control device may be a wall-mounted device such as dimmer switch, a remote control device, or a retrofit remote control device. The control device may include a gesture-based user interface for applying advanced control over the one or more electrical loads. The types of control may include absolute and relative control, intensity and color control, preset, zone, or operational mode selection, etc. Feedback may be provided on the control device regarding a status of the one or more electrical loads or the control device.

A safety switch assembly for use on a movable device. The assembly includes a bracket, an impact surface that is held in position in the bracket, and a switch. The bracket and impact surface are clamped against the movable device. The impact surface is an easily replaceable component.

A cover assembly includes a main body, a closure member, gripping portions, and an identification tag. The main body defines an interior to receive a remote control and includes top, bottom, front, first and second side, and rear portions. The closure member is coupled to the rear portion and configured to move the rear portion between an open position, where a remote control is insertable into and removable from the interior, and a closed position, where the closure member is coupled to the bottom portion to secure the remote control within the interior. The multiple gripping portions are provided on the first and second side portions and configured to facilitate gripping of the cover assembly by a user. The identification tag includes a processor and is configured to communicate with an external device and operate to increase a conspicuity of the cover assembly for locating the cover assembly.
