User interface 205 typically comprises one or more ON/OFF switches such as, but not limited to, one or more individual switches, a dual in-line package (DIP) switch comprising one or more ON/OFF switches, one or more rotary switches, one or more push button switches, one or more reed switches (controlled by bringing a magnet in proximity to the reed switch), infra-red operated switch, or almost any variety of switch type. In some embodiments, user interface 205 comprises two or more different kinds of switches. For example, a first pushbutton switch could be used to set lighting control adapter 200 to turn ON illumination device 103 when power is first applied to lighting control adapter 200, while a rotary switch is used to provide a code to processing circuit 303, instructing processing circuit 303 when to apply and remove power to/from illumination device 103 as power toggles are detected.

In an embodiment where user interface 205 comprises one or more ON/OFF switches, each switch either applies or removes a relatively low voltage, such as 5 volts DC to processing circuit 303. The combination of “1's” and “0's” applied to processing circuit 303 via the switches is a code that processing circuit 303 uses to determine when to apply power to illumination device 103.
