I’m experienced with the Sanwa snap-ins (TE ahoy!), and near as I can tell, the screw-in variety looks/acts the same. I don’t have any personally, but pics and such seem they would feel/be the same.
I replaced the Sanwas on my 2nd TE with all Seimitsu snap-ins and I love them. Shortly after that, I received some Seimitsu all-black screw-ins and became disappointed. Quick breakdown is that the snap-ins are flat-top, and very low profile button height. They barely stick up over the base. Screw-ins are convex, and the height is a bit higher than Sanwa. I don’t like this.
Comparable height would be lowest-highest:
Seim Snap / Sanwa / Seim Screw (respectively): _ / = / E ( <- I hope that made sense)
Sorry I don’t have a picture at the moment to explain, but anyone who’s used them would know what I’m talking about.
So my question is, are the clear/translucent ones more like the snap-ins, or more like the screw-ins? Or for that matter, are they more like Sanwas in relative height? I’d imagine the plunger is Seimitsu in feel, so the spring is probably a bit stiffer than Sanwa.
