Demand Switches

Reduce electric fields in your home, improving your health and your sleep.  Your home feels more quiet and calm and you will sleep more peacefully.  Children can respond particularly well.

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 10A light circuits, is the Comfort 1. 

The Comfort 7 is the latest development.  It is able to detect and tolerate a residual current flow, which makes installation much easier.  

All switches come with capacitors, filtering out the incoming dirty electricity.

Demand switches need to be installed (circuit diagram included) by a licensed electrician.

Gigahertz demand switches have come out on top in tests by the German consumer's association. (2017)

Note, that other types of demand switches are available, but they can be complex to install and maintain.  For 99.9% of cases, the above 2 types are sufficient.  The Ultima series from Gigahertz is difficult to operate and maintain, and we have stopped recommending them for Australian conditions. 

For any further questions about the right switch for your individual situation, please call Buildingbiology Services.  We are happy to help.
