Frequently asked

How heavy is the HMX Su Color Blue R2?

It is a light linear, actuating around 45g with a 50g bottom-out, so the whole stroke stays gentle. Travel is shortened too, at roughly 1.8mm pre-travel and 3.6mm total.

Does the Su Color Blue R2 need lube out of the box?

No. It ships factory lubed and the application is clean and even, so most builders can run it stock. Hand-lubing is purely optional fine-tuning.

What is the stem and housing made of?

A T5 stem runs in a PA12 top and bottom housing, paired with a 22mm spring. That combination gives the switch its smooth, slightly muted poly sound.
