Popular Keyboard Switch Comparisons

GLORIOUS Panda

Gazzew Boba U4T (62g) and GLORIOUS Panda are both tactile switches with deep, fairly thocky sound profiles. The Gazzew switches have a shorter initial pre-travel before the bump starts and a rounder overall travel. They're also noticeably smoother from the factory. The GLORIOUS switches are scratchier and have more spring ping in their sound signature.
