Lychee UHMWPE Linear switches are inspired by lychee fruits and feature an UHMWPE stem and full nylon housing. UHMWPE is a unique material with a lower coefficient of friction than POM. It's a softer material that's self-lubricating, and highly resistant to abrasion. These distinct properties result in a smooth typing experience with a softened bottom, and top-out sound. 

Switches are sold in packs of 10.
Quantity 1 = 10 switches.
