touch sensitive lamp

If you don't know what the problem is you don't know how to repair it. Have you checked the obvious stuff, fuse, screwed connections etc? If the touch controller is fried it may be bypassable.

Yes, I've checked all the obvious stuff. My question about it being repairable could have been stated better. I don't know how these touch sensitive lamps work so I'm assuming there is some internal gismo (touch controller?) that is not functioning. If so, would it be a generic unit that is replaceable or would it be unique to the brand of lamp?

Yes there's an internal controller. I don't know if you might find a replacement from Ebay, or if it would be safe. The alternative is to bypass the touch switch.

Little bit vague. Depends on how it works. Some of the older ones merely picked up hum through your body and could be finicky about where they were operated, some ar capacitance operated and people used to polish them and the dirty polish shorted out the insulators between the touch bit and the rest making it whatever the touch equivalent of deaf might be called. Then again even corrosion of the bit that connects to the bit you touch can do it. I myself never had much luck with touch switches they would come on when not wanted, fail to turn off or just do odd things. I blame my magnetic personality. Brian

Some of them only need a brief touch a long touch will do nothing at all if its off, only if its been touched to on. What is the make of this device? Brian

Could be, might be.... but a picture or description would help or even modle number or something. I wouldn't have thought it'd be worth by-passing.

in general you can pick up hum from any metal connecteed to a human... When I designed a similar circuit we had a cmos chip behind it to boost and latch te signal

My giues is there si either a custom chip or a standard CMOS chip inistde. If its custom bin it.

Bin the control and either fit a physical switch to bridge them or link the wires and fit a switch in the lead from the plug to the lamp.

Plenty of touch sensitive switches on ebay for less than £3.

What type is the replacement bulb. It may not work with LED or CFL.

Yeah - probably easiest to chop it out and add a flex lamp switch. I had a table lamp fail like this and did just that - lamp is fine now.

Thanks everybody, looks like my best bet is to bypass whatever "internal controller" there is and fit an in-line conventional switch in the lead. For what it's worth here's a link to the make/model

Well if the company do still exist surely they might want to help? Brian
