A control device configured for use in a load control system to control an external electrical load may provide simple feedback regarding the operation of the control device. For example, the control device may comprise a base portion configured to be mounted to an electrical wallbox or over a mechanical switch, and a control unit connected to the base portion. The control unit may comprise a rotation portion rotatable with respect to the base portion, an actuation portion, and a light source. The control unit may be configured to control the light source to illuminate at least an illuminated portion of the actuation portion in response to actuations of the rotation portion and the actuation portion. In addition, the control unit may provide a limit indication on the illuminated portion by blinking the illuminated portion when the electrical load has reached a limit.

A battery-powered control device may be configured to control an amount of power delivered to one or more electrical loads and provide various feedback associated with the control device and/or the electrical loads. The feedback may indicate a low battery condition and/or the amount of power delivered to the one or more electrical loads. The control device may include a light bar and/or one or more indicator lights for providing the feedback. The control device may operate in different modes including a normal mode and a low battery mode.

A knob assembly includes a front panel, a knob located at a front side of the front panel and configured to rotate based on operation by a user, a knob shaft that is coupled to the knob and that extends through the front panel, a supporting pipe that receives the knob shaft and that supports the knob shaft, the supporting pipe being configured to maintain a position relative to the front panel, a valve configured to control supply of gas to the appliance, a valve shaft connected to the valve and configured to control the valve to adjust a flow rate of gas based on rotation of the valve shaft, and a joint that couples the knob shaft to the valve shaft and that is configured to transfer at least one of a rotational motion or a linear motion of the knob shaft to the valve shaft.

A mouse device comprising a base, a first circuit board, a scroll wheel bearing, a light-emitting component and a scroll wheel. The first circuit board is disposed on the base. The scroll wheel bearing is mounted to the base. The light-emitting component is disposed on the scroll wheel bearing, and is electrically connected to the first circuit board. The scroll wheel is rotatably connected to the base and the scroll wheel bearing. The light-emitting component is disposed between the scroll wheel and the scroll wheel bearing. By disposing the light-emitting component in the scroll wheel, the light emitted from the light-emitting component would pass through the scroll wheel and the scroll wheel bearing to the outside, which can be evenly emitted from each side of the scroll wheel and the scroll wheel bearing for even light distribution and scrolling without obstruction.

The present invention relates to a control system and components therefor, the invention has particular application in adjusting the brake bias in a vehicle. The control system of the present invention may provide greater usability than existing brake bias control systems due to features such as allowing a display screen to be seen at a glance and the ability to zero the count shown on the display.

A control device may be configured to control an amount of power delivered to one or more electrical loads and provide various feedback associated with the control device and/or the electrical loads. The control device may be a wall-mounted device or a battery-powered remote control device. The feedback may indicate the amount of power delivered to the one or more electrical loads. The feedback may also indicate a low battery condition. The control device may include a light bar and/or one or more indicator lights for providing the feedback.

A switch structure includes a light-emitting part configured to receive power from a vehicle and to radiate light, a moving block located so as to surround the light-emitting part, a light-transmissive part configured to allow light radiated from the light-emitting part to pass through an opening in the moving block, and a film-printing layer located on a top surface of the light-transmissive part and including a symbol.

A load control device may be configured to control multiple characteristics of one or more electrical loads such as the intensity and color of a lighting load. The load control device may include concentric rotating portions for adjusting the multiple characteristics. A control circuit of the load control device may be configured to generate control data for controlling one or more of the characteristics of the electrical loads in response to rotations of the concentric rotating portions. The control circuit may be further configured to provide feedback regarding the control being applied on one or more visual indicators. The load control device may be a wall-mounted dimmer device or a battery-powered remote control device.

A rechargeable battery jump starting device and a battery frame for use in an electronic device such as a portable rechargeable battery jump starting device. The rechargeable battery jump starting device maximizes the power conducted from the rechargeable battery to a battery being jump started.
