Sensky 12V 24V DC Touch On/Off Sensor Switch Touch Dimmer Switch Brightness Adjustment for LED Cabinet Light, LED Strip Light, Rigid Light Bar

I used this as a controller for a piano music light.The whole body of the controller is touch sensitive. Touch briefly to turn on/off; touch and hold to change brightness (releasing then holding again to change direction). I love that it retains the brightness setting and fades in/out when turned on/off. Unfortunately sometimes touches that I meant to be brief on/off touches are taken as touch and hold (partially because I usually am feeling for the controller which is installed in a somewhat concealed location, but it also happened sometimes while testing as I built the light).To make the install a bit cleaner, I opened the case and soldered the leads from might light directly to the circuit board inside. The case has a couple of screws on each end, then the end plates come off. The circuit board simply slides into the solid housing. Short leads and my novice soldering skills made this a bit of a challenge, but it worked and I thought overall this item was well suited to the modification.

I love it, it works perfect.

Updated to 5 star:The first I received didn't work correctly or reliably. I was only able to get it to work twice in testing, then it would only come on full at full brightness with no way to dim, and the only way to turn off the lights was unplugging them.The replacement worked as intended but would turn itself off randomly. I contacted the seller and learned that the switch doesn't always work as intended if installed on metal. I had the switch on the aluminum frame of a 3D printer, once moved off the frame the switch worked perfectly.The support and responsiveness of the seller is rare and much appreciated.

Until it died it was a nice little device for led tape turn-on turn-off and dimming. Don’t waste your money on this. If dimming not important then get a super reliable in-line switch.

It's all in the description.

I like this switch a lot! It is small enough to place it anywhere in my desk area while used for the LED lights above the work area. The dim sensor is also a good feature that brings additional benefit for evening hours when I need to lower down the brightness of the led lights.

I can't believe this little beauty is less than 10 bucks. Went right in line in my 24 volt power supply and works like a charm. Not only does it turn the unit on and off but it gradually brings it up to whatever light level you preset and then gradually dims it back out. Cool

Dimming function works well and no flicker. Small and thin size is best feature.
