PS90 shows it's age/intended purpose with it's lack of accessory mounting options. There's a few methods people have tried to get a remote switch. One is custom wiring/button mounting on the inside of the stock but it requires a lot of cutting and such. The other option is velcro/double sided tape on a tape switch to the side of the grip. I'm going with option 3 and making my own mounts. It's still in the draft stage but I've got a working prototype now.
I had to extend the rail I designed for the light so the 7" modlight button cable would reach. This made the rail flex more than I'd like though. I'm going to se about reinforcing some spots by removing grooves but if that doesn't work I'll extend it some more and add a hook for the front of the receiver. This should fix any unintentional snags breaking the rail or the light flopping under recoil. It might be fine with some CF Nylon but I'm assuming most people don't print with that so I'm building it all with PETG first.
I wanted to keep it somewhat ambi so I'm using the finger guard as a mounting point for the button. It uses the existing screw hole but with a longer screw and uses the hex nut hole for some added anti rotation. It's just reachable for my tiny hands so once I get everything settled I'm going to make a version without the pic rail and only the button. It'll shave of about the depth of the rail and be a bit more comfortable to use.
