Tamperproof switched spur

[RF Lighting]

Hello chaps

I'm trying to source a switched spur which can not be switched off by mistake.

It is for a fridge in a public building. At present there is a non switched spur, but this is not really suitable for tesing and maintanence purposes.

The kitchen is not a commercial kitchen, and all the accesories are white plastic MK logic plus. I've had a look through their catalogue and can't find anything like this in the logic plus range (unless I'm being blind )


I was thinking something along these lines, but don't wan't to have to use metal clad.

I suppose I could spray it white, but that will probably look properly sh...

My only other thought was to grid it up, but I would prefer to use something designed for this application.

Thanks

Just by mistake? Or also by people who will try to defeat any security measures?

Surely a grid is designed for this - i.e. an application where you want a keyswitch and a fuse?

Bit of a guess here... could you use a 1G grid faceplate:

and a secret key switch:

Indeed, 2 gang grid plate with a white front. A fuse module and one of these.. http://www.tlc-direct.co.uk/Products/MKK4898.html

Or a 3 gang front and include a flex outlet.......



However, I find the grid flex outlets to be poor - It only takes a small tug to smach the front to pieces.

I don't think it will be subjected to malicious abuse, It just occasionally got switched off by someone tyring to be helpful by turning everything off at the end of their meeting (including the heaters, so it ends up with no heating for the next group)

I think this is looking like the soloution, but IMO it is not quite as neat as a plastic version of the key switch spur in my picture, and it means fitting a deep backbox to accomodate the depth of a fuse grid module

Maybe I'm just too fussy

Dual box, legrand key switch and fused spur.

Masterseal single-gang box with 2 grid modules...

Serious Q - is there an emergency isolation issue if you use a key switch?

 

[JohnD]

serious answer...

EPO button?

But why not a switch engraved "Fridge: Do not switch off"

 

[RF Lighting]

Do 5 year olds understand engraved switches?

 

[JohnD]

you didn't mention them before

put it high up then?

 

[RF Lighting]

There are wall units in the way.

I think a key switch really is the best idea. I'll get it engraved too if you really want

Seen a spur with a proper KEY switch on it, dont know the make.
Seen them on fire alarms , problem is they were RED.

Similar to the one in my pic at the top of the thread?
