Apparatus and methods for control of one or more functions within a premises. In one embodiment, the control apparatus comprises a "universal" electronic switch which can be configured according to any number of different desired functional and/or aesthetic schemes. The apparatus uses removable and replaceable control elements which are purely mechanical in nature, thereby allowing consolidation of all electrical functions within the parent control module. An improved control circuit including thermal overload protection is also disclosed, as are methods of operating and manufacturing the apparatus.
