Abstract
A wall switch device and a power outlet device are described. In one embodiment, the wall switch device includes a wall switch plate, a component integral to a receptacle on the wall switch plate, a control charging module, and an AC power input. The wall switch plate is fastened to a light switch module on a wall. The control charging module includes electrical contacts corresponding to electrical contacts on the component. The control charging module also includes a circuit board and an integrated circuit board. The AC power input supplies power to the component. Power from the AC power input is converted to DC power by the control charging module so that the power may be used to charge the component.
