…automatic removal of disturbing mains fields
Please note that these Demand Switches are not suitable for use in the USA
It is now agreed by many scientists and doctors in Europe and America
that our constant exposure to the electrical and magnetic fields given
off by all mains wiring can disturb the health of all of us - and not
just the relatively small number of extreme 'electrical sensitives".
NIGHT TIME PERILS
The bed we sleep in is literally surrounded by a cage of electrical and electromagnetic radiation. Because we use Alternating Current (AC) as our source of energy, this continually flows through the wiring in our homes and buildings and this creates these harmful electrical fields, even when everything is switched off. We generally sleep on mattresses which are full of metal springs which collect and radiate this negative energy into our bodies whilst we rest. Sleep is the time when our body repairs itself and if the body is subjected to electrical and electromagnetic stress during this time, the immune system is suppressed and prevented from carrying out its natural repair process fully.
Demand Switches work quite simply by shutting off the electricity at the fuse box, or meter. For example, fitted to the lighting circuit, when the last light is switched off at night (or during the day in daylight hours), the Demand Switch shuts off the electricity to the lighting circuit at the fuse box. Therefore, there is no current passing through the wiring and therefore no electrical radiation given off either. Fitted to a socket circuit however, the socket itself must be switched off otherwise a 'demand' remains on the circuit. Simple, yet 100% effective protection from electrical fields given off by the lighting circuit whilst we sleep, allowing the body to repair itself naturally. However, when the light switch is operated, electricity is restored to the circuit and the light operates as normal.
So the easiest and most effective way of removing these unwanted fields from our bedrooms in most cases is to use Demand Switches - and these are described below.

NT DEMAND SWITCHES
There are two models - the NT 16-plus and the NT 20-plus. They differ
only in the maximum load with which they can deal:
(a) To unprotected areas - fridges, boilers, etc.
Additional Technical Information
Supply voltage : 220V AC/5O Hz nominal but will tolerate 170V to 250V
Mounting (for non-DIN boards): optional bracket supplied (with screws
and wall plugs) together with terminal cover.
Full installation and operating instructions are supplied. The NT Demand Switch can normally be installed in 30 minutes or less.

ELF-NA7 - Comfort Electricity Demand Switch (220-240V) - 16AA Demand Switch? What for?
Electricity has become indispensable for every day life. The use of electricity inevitably causes alternating electrical and magnetic fields. The effect of these electrical and magnetic fields on the human organism has been the subject-matter of many international studies with all in all alarming results. Best to be on the safe side with a precautionary reduction of at least the “home-made” exposure to alternating electrical and magnetic fields.
A reliable Demand Switch optimised according to building biology criteria can substantially contribute to a reduction of your daily exposure without you having to forfeit any comfort. It is for this reason that experts recommend the decoupling from the mains (also often called “isolation”) as the first and most important technical step to be implemented when restoring with respect to alternating electrical and magnetic fields.
Our Demand Switch is installed in modern DIN distribution boards or next to older fuse boxes, and it is wired inline to the circuit to be protected. When there is no load on the circuit, that is, when everything is switched off on that circuit (icluding sockets if used on socket ring main), the Demand Switch automatically disconnects the line at the fuse box. When any switch or appliance in the circuit is turned on, it instantly restores power. To read Brochure please click here
Nominal voltage / capacity
230 VAC +/- 10 %, 16 Amp., 2300 watt filament lamp load
Mechanical durability of the relay
approx. 15.000.000 operating cycles
Residual ripple (nominal/typical/maximum)
< 2 mV / < 4 mV / < 8 mV
Building biology compatible low DC voltage (max. 8mA / 230 VDC)
Single-poled disconnection for optimum operator protection and minimum residual ripple. Overcoupling is optimally diverted with a low ohm output.
SafetyThe Gigahertz Solutions Demand Switches were the first “decouplers” ever to be VDE certified (the Association for Electrical, Electronic & Information Technologies), fulfilling strict safety regulations. VDE identification number: 40000677
The Gigahertz Solutions Demand Switches have been installed by many experienced electrical engineering technicians for many years. They are on the recommendation lists of renowned building biologists and are in use in thousands of households every day.
Using the ELF NA7 makes it possible to use house installation night-lights like inside light switches, or nighttime baby-lights. That means, when you have to pass a dark hallway at night you can still use orientation lights. Also, the ELF NA7 has a real-time protection system for high voltage protection integrated within it. These demand switches also act like lightning protectors as they are able to take out the lightning's energy and thus protect all devices behind the demand switch. Unfortunately the demand switch itself will be destroyed in event of this happening, but it will help to protect everything behind it, suchas cables, lights, TV, computer etc.
