Know before you buy
These are 5-pin MX-style switches, meaning they are compatible with most hot-swappable keyboards that support standard MX-style stems. If your keyboard PCB supports 5-pin switches, they will fit directly; if it only supports 3-pin, you may need to clip the two plastic guide pins.
No, these switches come pre-lubed from the factory. They are designed to provide a smooth, consistent feel right out of the box, so additional lubrication is generally not required unless you prefer a specific custom feel.
The 22mm two-stage spring provides a more consistent resistance throughout the entire keypress compared to a standard spring. This design offers a snappier, more responsive rebound, which helps prevent the key from feeling mushy.
Yes, the Haimu Sea Salt switches feature a transparent cover designed to allow light to pass through. They are fully compatible with SMD LED backlighting, ensuring your keyboard's RGB effects remain vibrant.
The dustproof wall design surrounds the stem to prevent debris and dust from entering the internal housing of the switch. This helps maintain the switch's smooth performance over time and increases its overall durability.
With an operating force of 47gf and a bottom-out force of 55gf, these switches fall into the light-to-medium category. They are designed for comfortable, long-term typing sessions without causing finger fatigue.
