Gateron Zealio

Gateron switches manufactured for ZealPC, commonly known as Zealios, are marketed as a direct upgrade path from Cherry MX models. They strongly resemble MX Tactile Grey switches in feel, though their springs are much lighter.

It appears that Gateron and ZealPC improved QC processes for Zealios, as they perform more consistently than regular Gateron offerings. They also seem to exhibit less friction.

Enterprising keyboard enthusiasts can create a similar switch by placing Kaihua Brown springs (60g) in Cherry MX Tactile Grey housings.
