Firstly, I'll start by saying that I have no electrical skills apart from basic changing a socket skills...
I have a small bathroom that I've decided to put a waterproof TV in. The TV is going to go in the centre of a stud frame attached to a brick wall. The wall has been boarded and will eventually be tiled. This is at the end of the bathroom, opposite the bath and sink with the wires already having been embedded behind the boarded stud frame.
The plan is to put the power adaptor for the TV in the loft above, running from a power outlet that I had wired up there, as I wanted to have the ability to switch the power to the TV on and off, so that the TV isn't left constantly receiving power fed into it (to avoid the possibly of heating it up and being damaged after a few years). I'm planning to put some kind of switch to the right of the TV, that would allow me to do this. My brother reckons this would be ok and so under his instruction, I've placed 2 2.5 T&E cables running behind the stud frame, that reach between where we intend to put the switch and the power socket in the loft. The plan is to insert the extra link of a switched fused spur (3A) between the loft power outlet to the TV power adaptor and place this switched fused spur in the bathroom, inserted flush in the tile wall.
As far as I can see by the diagrams I've looked at, the TV is going to be in the Outside Zone (not zones, 0, 1 or 2) so I could probably use a normal (non IP rated) switch but I would ideally like to use a waterproof switch, to prevent any chance of anyone with wet hands getting more than they bargained for when all they want to watch is Corrie!
I've considered using a PIR but didn't want to go this route as my Mrs will use the bath and possibly not move much whilst watching TV, so I don't want her to splash about to get the thing to come back on again. I've looked around on the net and the only waterproof switches I've see are for external use and look quite tough... I'd be happy with a small switch if possible. I've seen options like these:
A sensor switch that sits behind a wall and you just hold your hand near the tile to switch on or off - looked a bit pricey but I don't know what I'd need to incorporate this: http://www.sensor.co.uk/switches/bathroom_switch/
The Aquadesign and System Design IP 44 switches by Merten that are waterproof light switches - I can't see them anywhere to actually buy
The Clipsal switch - again, can't see this to buy anywhere apart from in Australia
The questions I have are: Is the use of a switched fused spur safe to do like this? Do I need (is it best) to use a switched fuse spur or is there some other way to go about this? Would a simple cover to go over a normal switch suffice, such as this: http://www.amazon.co.uk/Bathroom-Switch-Protector-Plastic-Waterproof/dp/B007VCTMS6?
To give a clearer idea of the environment, I've attached a photo so you can see where this is currently up to...
The tile wall will be finished in the same red tiles that are at the bottom and as there is white in the room, I'd like the switch to be discreet if possible to fit the room as it stands i.e. no industrial grey external switches.
Any suggestions, answers, etc will be gratefully received. Please feel free to ask me anything else if what I've written isn't clear.
Thanks in advance.
