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
