These are JoininKeys Sunset switches; use the same type of material as the Alpaca, manufactured by JWK. These are a linear switch in a 16-1364TCX VIBRANT ORANGE PANTONE colorway with a 63.5g gold plated symmetric long spring (also known as "slow" spring). JoininKeys Sunset switches are lightly factory lubed with JWK's P3 stem (a proprietary UHMWPE blend from JWK, same stem from their Durock POM linear switches).
