any switches would fit a hot-swap PCB as long as they are an MX-style switch. one thing although is the PCB, if your PCB supports 3-5 pin switches any switches should fit but if it only supports 3 pin switches you will need to clip the plastic legs (NOT THE GOLD PINS) off the bottom of your switch to make it fit. I would recommend either the Akko CS Vintage Whites which are an "Ultra-light" switch that has a lighter weighted spring making it easier to press down although you may accidentally press down sometimes, another great one as recommended is the Gateron Cap V2 Silvers which are more expensive but are extremely good switches designed by Gateron which utilizes their Cap housings which has a different Stem and housing design to provide for a different bottom out sound.
