A touch sensor? As in for waving your hand across and the light turns on / off?
I have that in my room, cause well you know you get bored sometimes and have the maplin catalog infront of you. It's kinda hard not to want to play with silly things. Instant problem was my door opens up past it, plus people walk in directly past it. So in retrospect it turns on / off all the bloody time and is now quite annoying.
I was thinking of sorting it out so that it's a touchpad instead so you actually have to touch it, but basically still lazier than flipping a switch heh
Goes quite nicely with the lighting rig I have in here though, because when my step-dad came down (who's a DIY nut), put in a recessive ceiling in the centre.. from that we then gave it a lip where a collection of 4 neon tubs are. They're only low-power things from philips that take ages to heat up, so you need to turn them on about 20minutes before you'll really need them; but once lit up they bounce against the light coloured walls to really give a much brighter light than a 100w bulb.
Next project is combining the computer desk with the cupboard so that I can basically slide things out from hidden places. Dislike clutter so-so much
I could be wrong about what you want, but usually speaking Maplin will have whatever you need. Often not too expensive about it either.
