Tealios come in 1 variant. The spring weight is rated at "bottom out" force, not actuation! Tealios have been tweaked with wobble reduction and improved smoothness compared to regular Gateron linears. Please note that PCB mounted switches can still be used in many plate mounted keyboards. As long as your PCB underneath has 2 extra holes next to the center post, it will support PCB Mounted switches and add extra rigidity to your build. If your PCB does not have the extra holes, then you can simply cut the small plastic legs off to make them Plate-Mount!
