I figured that might be the case and that the envelope was just for the samples - the Nashville distribution center can be a little rough on mail. ; )
Sure! Right now I’m testing them in Aflion Iceberg switches; you can actually see a photo from the swapping process here:
The Iceberg switches already had some two-stage springs in them, but I rarely used the switches because they were too light for me. The 80g springs make them much more enjoyable for me.
I also tried the springs in a different switch last night, probably something they’re much less likely to be used for normally: TTC Gold Brown V3 housings with Gazzew Phoenix clicky stems. The Phoenix stems are similar to typical click-jacket / “blue switch” stems but the shape of the clicky bit is different. I noticed that some part of that stem, likely this unusual jacket, experiences some interference with two-stage springs - the switch makes it past the tactile event, but hits a point just past that where it stops before bottom-out. Pushing just a little harder will produce a slight “crunch” sound and feeling that gives way to a normal bottom-out.
My guess is that the center tight coil is getting caught on the unconventional jacket shape - this is a very niche condition but I thought it could be possibly useful for you to know about the interaction. I’ve tried two other kinds of more traditional click-jacket stems that have zero interference issues with the two-stage springs.
