Convoy c8 remote pressure switch

Hi everyone. I’m looking for a remote pressure switch for my convoy c8 flashlight. I’m finding some things on eBay but I’m not sure of their quality so I’m hoping you guys have some recommendations. Thanks!

What do you think of this? https://www.aliexpress.com/item/32801326773.html

Most of ’em will have hair-thin wires that over the length (×2), can reduce output vs directly switched.

Someone here, though, made remote switches with a FET doing the switching right at the cap, though. Forgot who, but goggle around, or maybe someone who remembers will fill in more details.

Lexel had a prototype and it was Jared_M or g_chart who had one also, but that project was dropped due to not enough interest.
