A load control system having a controllable electrical outlet provides a low cost solution for controlling a plurality of standard electrical outlets. More particularly, in various embodiments, the present invention provides systems and methods for data de-duplication that may utilize storage reclamation. A compensation network is coupled in parallel to the parallel array of resistors in order to compensate for resistance drift caused by non-linear responses of components within the variable resistor. The auxiliary contact piece is guided in an electrically isolated manner. The recess preferably has a trapezoidal cross section tapering toward the first main surface and can be produced for example by sawing into the window.
