Preventing "Bottoming Out"
"Bottoming out" is a term used to describe when a key stroke is pressed all the way down where the stem of the switch hits the inside of the switch casing. This causes a "clack" from inside the switch. Switch sound dampeners are soft rubber O-rings that can be installed onto the keycap stem to cushion the landing of the switch by stopping the key stroke just short of the point of bottoming out. This also very slightly reduces the max travel distance of the switch.
The dampeners only affect the last 0.2-0.4mm of travel, so it does not affect the feel or sound of the actuation point.
This modification is popular among mechanical keyboard owners from around the world. Since most people will bottom out at least a fraction of their keystrokes, the switch sound dampeners will cut away extra noise giving your mechanical keyboard a consistent sound output while typing. The added shock absorption can also help with finger fatigue during long typing sessions.
Both models we offer have the same amount of noise reduction. The different thicknesses will only change the total travel distance.
40A-L Red 0.2mm Reduction
This model has minimal effect on the key travel so the switch will feel closer to factory specs. We suggest this model for most applications.
40A-R Blue 0.4mm Reduction
Reducing the key travel by 0.4mm will have a more noticeable effect on the total travel distance. This model is recommended if you find the current key travel too long.
