Review on 🎮 Onyehn Controller3V: Ultimate Control Switch Dimmer for Enhanced Performance by Ben Diesel

I use it to control the speed of a small built-in 12VDC (2.5A max current) bilge fan motor. The off position makes a nice audible "click" and saves me from adding another switch. I didn't try to work around this to see if there was a performance reduction on the "max width" setting. This would be disappointing so the rating may need to be adjusted if this happens. The average current draw definitely goes down as the pulse width gets narrower, which is great for reducing overall power consumption. My fan can run all day on a 16Ah battery. The controller doesn't seem to heat up and the finish/soldering looks decent. The thin capacitor next to the knob protrudes and bends easily, so be sure to mount it in an enclosure where parts and fingers will not touch.
