What customers say
The HMX Xinhai Linear Switches are highly praised for delivering exceptional value and performance in the budget segment.

Know before you buy
Yes, the HMX Xinhai switches come factory pre-lubed using an improved lubrication technique, which ensures a smooth keystroke experience immediately upon installation.
The 22mm KOS single-stage extended spring provides a snappier return and a more consistent resistance throughout the press compared to standard-length springs, resulting in a responsive and crisp typing feel.
These are 5-pin MX-style switches, making them compatible with most hot-swappable mechanical keyboards that support standard Cherry MX-style stems. If your PCB only supports 3-pin switches, you can simply clip the two plastic guide pins off the bottom of the switch.
The softer PA12 top housing material is chosen to refine the acoustic signature of the switch, typically resulting in a slightly deeper and more muted sound compared to harder plastics like polycarbonate.
The operating force of 55g is the pressure required to register a keypress, while the 62.5g bottom-out force is the pressure needed to press the key all the way to the bottom of its travel. This difference provides a comfortable resistance that helps prevent accidental keypresses.
