Hi,

We have installed some wall lights, the touch ones with three settings. We have a issue that they keep coming on randomly. Even when nobody is in the house they come on when they come home. It's on a TT system, could it be a appliance in a cycle? Small spike in voltage? or a ghost? The lights have been replaced once. Anyone come across this before?

Are you sure they're properly earthed?

if you miss those days, try the amish community. they still won't use electrickery or automobiles

As long as you have a cover over you in bed, nothing can get you :)

And remember to snuggle down deep so your head is covered. No monster or ghosty will get through your duvet.

Firstly, You need to ensure that you have a good earth, so that the fitting can not pickup stray RFI signals.

As its a TT system, the ZS at the fitting will be in the region of 10-200 ohms, and not fraction of ohms.

The control electronics is being triggered by radiated RFI or conducted RFI.

If that's the case then the control electronics in the fittings are a bad design.

If the interference is conducted type then You will need to fit some type of HF filter,
in-line with the fitting supply, or convert to TN-C-S.

If its the radiated RFI, then you can not do much but to replace the fittings with a different make.

I have a table lamp with inbuilt touch sensitive switching/dimmer. It comes on every time the computer is turned on and every time the scanner is used, they are in the same room. Earthing is good (PME). I have got used to turning it off, one two or three taps depending on how bright it is. I have always assumed it is transients much harder to get rid off than ghosts. One day I will get around to turning it off at the socket.

Why put off until tomorrow what you can put off 'till next week.

I think he means that it shouldn't be too old, and be fit for purpose. Perfectly reasonable.
In the current climate of austerity, i can't afford to change my old cover, I may never be able to!!!

How often does tel get a new bed-cover for himself? and how can he afford it??

serves him right for fitting wall lights. these went out with the demise of gas lighting.
They wanted them in their bedrooms. The fittings are actually quite nice.

The weird thing that they don't come on in pairs. Just randomly.

Touch switches that replace ordinary plate switches rarely use a neutral connection. As a consequence the electronics is often prone to false triggering by mains bourne transients or strong radiated RFI. There are a couple of things you can do to minimise this effect:- 1) Ensure the CPC is connected to the metal back-box. 2) Connect a mains rated CR (typically 0.1uF in series with 100Ω) snubber across the switch terminals. If the touch switch is currently mounted in a plastic cavity wall box, try changing the standard plastic box for the less common foil lined or metal type which has a CPC termination connected to the foil.
