Demand Switches are installed into the fuse box. They eliminate electric fields by turning off the circuit they are guarding, when no current is flowing. Sleeping amongst electric fields is a health hazard.
When you turn off the last appliance (e.g. the bedside lamp), the switch senses that no electricity is used and disconnects the circuit in the fuse box, giving you and your family a safe night's sleep (of course, it works also during the day). When you turn your light on again, it re-connects within a 50th of a second.
The functioning of other appliances, like the fridge, is not affected, as they are not connected to the same bedroom circuit.
We are offering various types of demand switches, depending on your needs. The simplest version, which works for most situations, is the DS Comfort 1.
The Comfort 7 and 8 switches are the latest development. They are able to detect and tolerate a residual current flow, which makes installation much easier.
For particularly difficult installations, Gigahertz developed a the Ultima range, which can switch off, even though up to 100 Watts of power is drawn as a base load.
Demand switches need to be installed (circuit diagram included) by a licensed electrician.
Gigahertz and Biologa demand switches have come out on top in tests by the German consumer's association.
For any further questions about the right switch for your individual situation, please call Livspace. We are happy to help.
