Factory assembled Bobagum Silent Linear Switches. Sold in packs of 10.
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 of the switches 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 inconsistencies. https://youtu.be/8ZSlVkCLBWY
