The Lord of the Tools Push On/Off Rotary Trailing-Edge Dimmer Switch 0-10v Dimming Power Supply Dimmer Knob NO Polarity Switch for Dimmable LED Incandescent and Halogen Bulbs White

I like this product it works very well.

I ordered two of these. First one I tried didn't work, the 0-10 volt output was only 0-0.3 volt. Second unit works well. It isn't push on/off as stated in title but rotary motion as stated in description. I prefer this actually. Anti-clockwise all the way with a click turns off AC voltage and 0-10V drops to 0 volts.Comes with good instructions. A little on the pricey side. I paid £16.69, would be better around £10.I like that these units don't have led lights, perfect for an ebmpapst fan I have in the bedroom that accepts a 0-10 volt signal for speed control. Let's see how long this lasts...I will update this review in due course

As others have mentioned, this is not a push on/off dimmer but has a switch at the start of the rotation.The AC out on mine worked correctly, switching off when it should. The 0-10V output worked correctly as well.There are a couple of issues for UK installations:1) The body of it (Under the faceplate which covers the screw holes) is a little too small for a UK pattress box which means that it wants to fall inside the box if it isn't aligned perfectly.2) It's quite a deep unit with the terminals right on the edge so you might need a deeper box, depending on the wiring you have.3) The supplies screws are M4, but a standard UK pattress box takes M3.5 screws.It would be nice if it had a switch to select between 0-10V and 1-10V outputs, but it is just a fixed 0-10V output as described in the listing.It's a bit pricey, but it has a reasonably nice feel compared to some dimmers.

It works to a degree, but not as described.Firstly, as previously mentioned, it's not push on/off. You turn it all the way down, then it clicks.However, the click doesn't appear to do anything. On the example I have, the AC OUT terminals are always live, irrespective of the position of the knob. I've tested this with a multimeter (as the lamp is already off as the 0-10v output is at 0v), and they are always live. The description doesn't explicitly say that AC OUT is switched, but it is implied both from the text and from the wiring diagram showing AC OUT being used to switch a contactor.Two stars rather than one, as the 0-10v output does work as advertised.
