STBTECH 12V LED Touch Dimmer Switch Concealed, DC 3.7-24V 4A Touch Switch Sensor for Smart Home LED Light Strip, Penetrable Wooden, Stone,Glass etc, No Holes Required(Dark Gray)

worked like a charm - and that through 2 cm marble (was sceptical whether it would make it and had to be careful to have the leads not interfere - i.e., move them straight away).it DOES have a soft on/ off.i have a 20W load on it (24V) and it is really quite impressive. very happy.

I have purchased three of these for control of 24VDC LED COB strip. Constant voltage 24VDC LED drivers as supply.After much experimentation, I conclude that they do not work at 24VDC supply. I purchased multiple times to ensure that one instance was not a 'dud'.Operation (of all three) is perfect off my bench DC supply at 23V (and down to 5V as tested) but they simply do not work at 24.0VDC as output from standard 24VDC LED drivers.Behavior is that small blue internal indicator light flashes on briefly when connected to that 24.0V supply, and that is it: no on-off function and no dimmer function.Exactly the same device works perfectly at 23V DC; full on-off and dimmer function.Essentially these appear 'sensitive' to voltage supply at the upper range of their quoted working range.I have had to substitute with different touch switches for my application.

Easy to wire up. Blue and green to light. Black and red to power. Works flawlessly. Got 2 in my camper conversion. Much neater than switches. No power drain when off.

Easy to fit but very temperamental! Turning on sometimes works first time but off is definitely not easy. When the dimmer works it is a good feature.Would not recommend

works well through 16mm chip board. my only criticism is that there are no wiring instructions other than the picture in this advert and my one had different coloured wires, two red one black and a yellow.

Do you have a touch enabled shed? I bet you hadn't even thought about having a touch enabled shed so I'll tell you about mine. I bought three of these and mounted them on the inside of the cladding boards (approx 20mm thick), connected to led light strips powered from an old van battery that is kept charged with a solar panel on the roof. The shed now has three external touch sensitive zones, none of them labelled or marked in any way as nature intended. As with all things of uncertain location a stroke in the general area enables a better chance of contact than a single press. Stroke the shed next to the door and the overhead porch light comes on. Stroke the shed near the corner and the decking underlights come on, a little further to the right and you'll be treated to the eaves lights. Linger with your hand in one of the zones and the light dims or gets brighter. If you are a man who loves his shed, prepare to renew your vows.So having been thoroughly carried away with the sheer excitement of it all the bottom line is this. These might be very cool inside the house (until you get sick of wiping finger marks off the wall and replacing transformers - these are not 240V) but they are utterly amazing in the shed. No need for external rainproof switches, no drilling through the cladding, no having to mask anything when it is time to put on another coat of preservative. Total game changer.

Installed behind a 22mm board and it doesn’t work properly.Pressing briefly on the surface sometimes works but very often does nothing.Pressing for a long time gave me better results and increased/decreased the intensity of the lights.The positive is that the instructions for installing it are sufficient.The adhesive supplied with it is extremely strong so it’s impossible to remove it without breaking the switch. So, no return possible: very clever on behalf of the manufacturer.

Easy to fit and works through 2cm of marble.
