Add this to your bedroom or living room’s electricity circuit and reduce the electric and magnetic fields by isolating the supply of electricity so that it’s only available when you need it.  For example, if you have turned off your lights, the demand switch turns off the electricity to that circuit. When you turn a light on, the demand switch senses that, and restores power to that circuit immediately.

If you don’t already know it, the Gigahertz Solutions NA7 is simply the best: it is the only demand switch EVER to be awarded Germany’s VDE certification of proven product safety, with tens of thousands installed over the years.
