Remote switching and NVR units

[Stree]

Just got a bargain from Lidl.
2X remote controlled plug units ( single) that mount onto a standard socket If the socket is switched its just left "on" and the remote unit takes care of the on/off switching.
These are rated up to just under 3000 watts and are rated for external use and have clear flip up front shields.......No rain in the workshop but handy for dust protection! . The remote works from 30 feet away even when pointing the remote away from the switch. ( Might be more, just what I tried in my workshop )
There is a learning program built in so there are separate on/off controls on the remote for each unit.. Even has batteries included.
£7.99. and guaranteed for 3 years.

I have only used one of the units so far, on a pre NVR switched dust extractor, and its made a big difference. Rather than walking 12 foot from the saw or 20 foot from the P/T to switch on the dust extractor , I keep the remote handy and just switch the extractor on and off as needed.

So. Decided to buy ( have bought ) a pack for someone I know that has a similar machine shop and I know it will be useful but.......His extractor has NVR switches, so I assume this wont work?
I have heard there is a way round this, anyone know of it?

Wire the NVR coil to a separate 13 amp lead & plug (with 3 amp fuse) and ensure that both sides of the coil are disconnected from the rest of the contactor. Permanently power the extractor and switch the coil with the remote.
The remote units I have, have their own NVR action anyway.

I'm using the same Lidl socket on my dust extractor - makes life so much easier. I originally bought a pack of three Byron remote sockets from B&Q but they are now reassigned to switching the table lamps in the living room.

The thing with using them in the workshop is that getting to the dust extractor is awkward and it makes working so much easier.

Although the Lidl sockets are waterproof (IP44) they have to be plugged directly into another standard socket. I was hoping that they would be a waterproof socket on the end of an extension lead so that they could be plugged in indoors and remote control things outside. Still they do what I want in the workshop and they were cheap - on the other hand they are not as well made as the Byron ones and are bigger and 'clunkier'

Thanks Bob, I think I get that, just take to NVR coil out of the circuit and run the remote switch through 3 amp circuit, leave the unit in the powered state and control by the remote,
is that right?

Thanks for the input

Misterfish, I have an outdoors circuit as well, so I could rig up a remote there too if I can think of a use, although they are fine for workshop use, if its water proof its dust proof by default......

good idea stree
the ones i have are used for switching on/off christmas lights and are only rated to 1000w
i got around the problem of switching the dust extractor on/off by fitting a 13amp ring main socket directly above the table saw and switching from there , the dust extractor came with a very long lead

Yup spot on. Most NVR have both coil connections out to separate terminals and then links to the power input via the stop start push buttons.
Do make sure the coil is completly isolated from the main power feed though. ABSOLUTELY essential that the pins of the plug going to your remote switch can ever become live via the main power feed.

Good Luck & Happy Christmas
