Haimu Heartbeat Silent Linear Switch (10 Pack)

Brand Introduction

Haimu has quietly become a respected name among switch enthusiasts for delivering smooth, refined, and affordable mechanical switches. Crafted with focus on consistency and a muted acoustic profile, their Heartbeat series has become a go-to silent linear option for users seeking quality sound without rubber dampening.

Product Description

The Heartbeat Silent Linear features full Nylon PA66 housings (top and bottom), with a POM stem—a classic build that balances smoothness and durability. Instead of rubber pads, its silence comes from a clever stem mold design featuring flexible legs that dampen sound organically. Pre-lubed at the factory, this switch offers a clean, silent typing experience without sacrificing tactility or definition. 

If you don't like "mushy" silent switches, this is for you.
