Introducing the Gigahertz Solutions NA7 Demand Switch: The Ultimate Solution for Reducing EMF Exposure in Your Home

The Gigahertz Solutions NA7 Demand Switch is the perfect solution for reducing your exposure to electromagnetic fields (EMF) in your home. Designed to be mounted in your fuse box, this demand switch automatically interrupts the mains voltage as soon as the last consumer (e.g., a bedside lamp) is turned off, and switches the mains voltage back on automatically and without delay as soon as a consumer is turned back on.

Reduce EMF Exposure with the Gigahertz Solutions NA7 Demand Switch

Add the Gigahertz Solutions NA7 Demand Switch to your bedroom or living room's electricity circuit and reduce electric and magnetic fields by isolating the supply of electricity so that it's only available when you need it. The demand switch senses when the last consumer is turned off and automatically turns off the electricity to that circuit. When you turn a light on, the demand switch senses that and restores power to that circuit.

Proven Product Safety: Germany's VDE Certification

The Gigahertz Solutions NA7 Demand Switch 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. Rest assured that this demand switch is the best on the market when it comes to your safety.
