Double pole 20amp isolator with Key

[sythai]

Hi chaps...

Where can I get one of these, customer wants to be able to lock off supply every night by turning key off and taking out (as opposed to actually having to put seperate padlock on isolator)

hope that makes sense

use a contactor on with a key switch next to it

Or can you use one of these ifs its just one circuit MK 20A DP 1 Way Secret Key Switch - Grid Plus Switch Module - QVS Electrical Supplies | Electrical Wholesaler

Or if you want a proper key , but still only one circuit maybe [ame=http://www.amazon.co.uk/Metal-Clad-Double-Pole-Switch/dp/B0032P5HUI]MK Metal Clad 20A Double Pole Key Switch: Amazon.co.uk: Books[/ame]

It would be a good idea if you told us what the supply and why he wants to lock off?

With a fish key (which are easily obtained) it can be easy to be switched on by someone he may not want switching it on also a lot kit that comes with a key I have found is a 455 key which again is easily obtained.

Thanks chaps.... yep this is the sort of think I'm after cheers Andy

Going to be used to isolate a roller door supply. (Dont actually need it to act as switch up and down, have seen key ones like this already, customer has remote to control this)

Hopefully these ones cant be picked? More of deterent than enything and customer will lock away remote each night also.

Thanks again,

Sy
