1. A remote control device configured to be mounted over an installed light switch, the light switch having a switch actuator configured to extend through a faceplate, the switch actuator operable to control whether power is delivered to an electrical load, the remote control device comprising:
a base portion comprising a first opening that is configured to at least partially receive the switch actuator when the remote control device is mounted over the light switch, wherein the base portion comprises an arm configured to be located adjacent to the switch actuator when the remote control device is mounted over the light switch, the arm configured to bias a surface of the switch actuator against a surface of the first opening to retain the base portion in a mounted position relative to the switch actuator;
a rotating portion configured to, when the remote control device is mounted over the light switch, receive a battery and a portion of the switch actuator, the rotating portion configured to be supported by and rotatable relative to the base portion;
a printed circuit board disposed in a cavity defined by the rotating portion;
a wireless communication circuit mounted to the printed circuit board; and
a control circuit that is mounted to the printed circuit board and is responsive to movement of the rotating portion, and the control circuit communicatively coupled to the wireless communication circuit, the control circuit configured to, in response to movement of the rotating portion relative to the base portion, cause the wireless communication circuit to transmit a control signal that causes an adjustment of an amount of power delivered to the electrical load.
