Feyachi PS-16 Remote Pressure Switch 1" Flashlight FL9 FL11 FL14 FL17 FL22 IED Flashlight, Won't Fit WL15

Worked with my Ultrafire 501B. I like this one a lot better than the other pressure switches I've used before where instead of squeezing a plate to activate it there is a nice and tactile clicky button that activates the light. It has multiple modes of clicking too so you can toggle and switch it on and off.

This item does not fit. Would like a refund.

It works fine except one thing when the cap is fully on it doesn't work. However when the cap is on 3/4 of the way it works fine. No other problems.

Feyachi PS-16 Remote Pressure Switch 1" Flashlight FL9 FL11 FL14 FL17 FL22 Tactical Flashlight, Won't Fit WL15 WL18Very good quality product works great no issues would recommend this product.

I bought the whole flashlight kit and this was in the box, over time, about several months, it last for a long time until the connector to the part that screws onto the flashlight just came undone on its own.Making the flashlight useless in my rifles. But when it works, it works really well! It’s super easy to put together and it’s a cheap replacement for the part.
