Broken-in Full-POM JWK Pianos
Sold in packs of 10.
The original broken-in Piano switch! These are JWK/Durock Piano switches that have been mechanically broken in for 1.2 million actuations. The POM sliding on the POM simulates years of use, creating a smoother feel just like the vintage switches we all desire - without the dust, desoldering, ultrasonicing, spring swapping, and thrift shopping. This is especially prominent with the all POM Piano switch, as the material is self lubricating and really benefits from a break in period before lubing.
Lubing Recommendation
205g0 or bust. These linears benefit from a nice thick lube. Give the whole stem a nice light coat, and give the bottom housing sliders a medium coating. I also recommend a spring swap and oiling, as the stock springs are rather heavy, crunchy and overall not so good.
Kelowna Films are recommended for these switches.
Device Information
I custom designed the machinery for this, and as a mechanical engineer you have my word that these switches are being broken in on precision machines, and not some silly "rock taped to a fan" device. This helps keep the stresses on the leaves to a minimum, as the pressing is no harsher than your fingers. The machine also introduces extremely slight oblique presses, as we never have perfectly centered and straight down presses when we type. This helps to wear the switches evenly and effectively.
Disclaimer
Sales on worked in switches are final, as this is a product with a service rendered upon it.
