    How does a demand switch work?

    Basics:
    A domestic power circuit produces two types of "electrosmog": alternating magnetic fields and alternating electrical fields. While the magnetical fields "disappear" as soon as the appliance is switched off, the electrical fields remain present and a problem in the complete electric circuit all the way to the switch or to the empty socket even after switching the appliance off

    This is where the demand switch sets in:
    Having been installed in the domestic fuse box, it will automatically interrupt the intended power circuit as soon as the last appliance has been switched off. The interrupted circuit is now free of electric tension and can therefore no longer cause any electrical fields. Especially for the sleeping area this is an easy way to keep the room free from low frequency alternating fields.

    Comfortable solution for the user:
    As soon as any appliance is switched back on, the demand switch will recognize this and automatically and without delay return the electric tension onto the power line. This means, you don't even take note of the interruption in your everyday life.

    The determining elements for the operation of a demand switch are:

    • A power sensor to find out whether electricity is needed or not.
    • A power relay which will connect or interrupt the electric circuit with the power grid.
    • A cascaded rectifier circuit to generate a for building biologists uncritical DC control voltage which will control the interrupted circuit in order to detect a new demand for electricity.
    • And, of course, a control circuitry to make it all work reliably.
