lighted china cabinet
i have a lighted china cabinet that the "touch control" went out on. the light stays on but will not dim/turn off using the "touch hinge". bought 2 different replacement units that control it and one worked 2 times and the other one never worked. my REAL question is what makes this thing work? does the wire to the hinge activate a micro-relay or something when you touch it? not real big on electrical printed/composite circuits! any info. will be appreciated.

It works basically on a principal that the electrical trade frowns on.....Shorting your fingers to ground.. It works similar to a GFCI, by recognizing stray "Current" and provoking a response.
Does this happen to be on a carpet?....Mine wouldnt work until I put it on a hard wood floor.
Try an electronics supplier, they have a special spray that can be used on electronics to clean and dissipate static electricity. Clean the hinge.....
I realize maybe its a bit tough, but touch your left hand to the metal of the "LAMP FIXTURE" and Right hand to the hinge. If it works, ensure you have a clean hinge, and the "Trigger" wire is Clean and tight.

It works by responding to a change in capacitance, essentially the physical property of how much charge an object can store. The detector puts a small charge onto the metal surface, when you touch that metal a portion of the charge flows into your body and the circuit detects the overall drop in charge of the metal surface. The circuit can then use a semiconductor such as a triac or thyristor to make the lamp brighter or dimmer based on the touch.
This type of circuit does not work with a compact fluorescent (CFL) or fluorescent bulb; that could be the problem if you've recently changed it. Obviously a broken or loose wire somewhere in the circuit would inhibit proper operation. It may not even be obvious; perhaps a corroded connection between dissimilar metals (like copper wire and anodized steel hinge).

Both guys pretty much hit on the nail with thier suggest to slove some of the issue you got there.
some case if you have very dry house it will cause this issue as well what i heard.
Merci,Marc

thanks guys! i knew i could get some info here. my house IS dry,as french said. never heard that before.NEVER TO OLD TO LEARN!! i'll try touching both maybe it will work. i did re-tighten the screw that the wire is attached to and it did not help. it is less than a year old, but it was a floor sample thus no warrantee. it worked until about a month ago when it just stayed lit. i'll post back if i can't find the problem.
