Used for a panel mounted control of a PWM LED Dimmer in an application were I wanted "OFF" to be completely "OFF".The power switch is isolated from the potentiometer and has a very strong sounding snap action, which I used to control the 120V power to the LED DC supply. So when it's OFF, it's OFF.

I used these switched potentiometers to switch and dim low voltage LED cob lighting strips. So far they have proven durable and very functional. The anodized aluminum know adds a bit of class

Pretty cheesy control, but I could not find anything else with an AC switch and had to have that for this application. It is so flimsy that soldering to the tabs bends them. Pretty poor overall. I really needed a 1 Meg pot, but tested my radio at 500K and seemed to work OK. I was replacing the tone control/power off/on switch on an 87 year old Breting 12 shortwave receiver. Just breaks my heart that I was forced to put this import crap in this piece of history. I'll keep checking the auction sites for a more suitable part. This works in the interim, but I don't trust the switch and unplug the set when not in use.

They do what they are supposed to but the one-off is stuff and a bit flimsy.

These 100k pots are Single Linear Taper which are perfect for dimming Meanwell drivers for HLG LEDs. Simple and effective. I find at around 15-20% my 320w Meanwell driver will turn off any power to the LEDs but even for seedlings at 2 feet above the plants 30% dimmed is perfect! 100k are ideal for a single driver setup. Do your homework and select the right Ohms for your situation. White wire on the left pole, blue wire on the middle. Keep it simple!

These are kinda crap, unfortunately. Used as a replacement switch for my Zadro Lighted Mirror. Switch is flimsy and the connection inside is loose, causing the light to flicker. Since it comes with two switches, I'll try the other one tomorrow. Hopefully it will be better.Update: Soldered the second switch on, works just fine. must have just gotten a rotten one. With that being said, I think this company sent me an extra order of switches. Received them today. That was nice of them. I don't want to change my review on these switches because it was the truth, but I will update the stars from 2 to 4, losing one star for the inconvenience of having to replace the fist one.
