The most commonly used demand switch. Reliable and suited to almost all situations.

Demand switches work automatically, you don't need to do anything!

Functions of Comfort  NA7:
  • Works reliably also with dimmers, fluorescent lamps, energy saving lamps, halogen lamps and start-up electronics.
  • Orientation lights in the light switches and infant night lights also work with disconnected power flow.
  • Reverse and excess voltage protected.
  • LED light to show disconnected power.
  • Residual ripple: < 4 mV.
  • LED-supported function-diagnosis for easy installation and operation.

The TOPSELLER among the demand switches!

Compared to conventional demand switches, the NA7 has the following advantages:

Easy installation without complicated adjustments to the local situation or installation of additional base load elements.

It reliably works also with electronic consumers (such as rotating dimmers, vacuum cleaners, switching power supplies for instance for halogen ceiling lights)

The DC control voltage and a cascaded rectifier circuit forces the critical residual ripple down to only few millivolts. The system control lamp which comes with the device allows an easy and constant function monitoring.

It also serves as excellent lightning protector in the case of excessive voltage due to a lightning strike in your neighbourhood.

Reverse polarity protection: If phase and neutral are accidentally wired the wrong way, this will be signalised and so protect you from installation errors.

Resumes functionality autonomously after an electric power outage.

Minimum turn-on delays and short turn-off delays, without risking instable switching status
