Factory assembled Gazzew U4TX Tactile Switches. New plastic with dustproof silent long pole U4TX stem. These new stems feature the same silencing that is found on the U4 of bobagum switches with the same tactile bump profile of the U4T with a long pole. It makes for a unique long pole switch with a twist. Nicknamed Half-Thocks because they are silenced on the upstroke and partially silenced on the downstoke. Sold in packs of 10.
Prototype U4TX Sound Test.
I recommend trying Gazzew Springs if the weight you are looking for is not in stock. Gazzew springs are a nice improvement over the stock springs and increase snappiness and the pronouncement of the tactile event https://kirballskeys.com/gazzew-springs/.
If you disassemble your switches please watch this video on the correct assembly procedure to prevent damaging the leaf and causing inconsistent tactility. https://youtu.be/8ZSlVkCLBWY

An improvement over the U4T
As a fan of the original U4T, I give these switches 5 stars as a welcome upgrade for folks who want a quiet upstroke and reduced stem wobble. If you ask me, these are the new king of thocks. Pros: - Same practically binary tactile feeling as the U4T. - Very muted upstroke. The sound of the upstroke is nearly unnoticeable when typing. Think "Thock" instead of "Thockuh" - No "ping" even without lube - Significantly less stem wobble than standard bobas thanks to the box design. (still some wobble, but it doesn't help that I'm using tall keycaps) Cons: - Slightly scratchy feeling without lube - Actuation force feels very high (65g springs were all that was in stock). Lube should reduce this but I haven't tested. My fingers need time to get used to this, because for now I find myself not pressing hard enough and missing keys. My main warning is that if you don't like very stiff keys, you *must* lube these or swap in the lighter springs.
