Patent ID: 8450875

Claim:
An apparatus for controlling at least one electrical load, the apparatus comprising: at least one pushbutton; a communications interface for communicating with the loads; a control logic and at least one first controlled switch; wherein the at least one controlled switch and the communication interface are driven by the control logic; wherein the control logic includes an input for an input signal; wherein the at least one pushbutton generates the input signal for the control logic, and wherein the loads are switched on and off by the input signal generated from the at least one pushbutton via the communications interface; wherein the at least one first controlled switch is connected between the loads and a power supply, and wherein the load is supplied with voltage through the generated input signal of the at least one pushbutton via the control logic through the at least one controlled switch, the first controlled switch, when the load is switched off, isolates the power supply from the loads as soon as all of the loads have been disconnected via the communications interface, and the first controlled switch, when the load is switched on, applies the power supply to the load and the control logic shortly after outputs the input signal as a control signal to the communication interface.
