HMX Xinhai Linear Switches

This linear mechanical switch suits users who prefer smooth, consistent keypresses without tactile bumps or clicks. It fits well for typists and gamers seeking a straightforward, responsive feel with moderate actuation force. The switch is not silent, so it may be less ideal for quiet office environments.

Feel & Sound

The switch provides a smooth linear keystroke with no tactile feedback or audible click. It has a moderate actuation force, offering a balance between light and heavy keypresses. The sound is typical for a non-silent linear switch, producing standard mechanical noise without dampening. Users should expect a clear but not loud typing sound.

Actuation Characteristics

With a short pre-travel distance, the switch actuates quickly, supporting fast keypresses. The total travel is standard, allowing for comfortable bottoming out without feeling too shallow or deep. This makes it suitable for both rapid input and longer typing sessions.

Build Quality

The switch uses a POM stem, known for smooth movement, combined with a nylon blend housing that adds durability and reduces friction. The spring length and force variance suggest consistent performance across units. Factory lubrication is applied, which can improve smoothness and reduce scratchiness, a common issue in linear switches.

Compatibility

It is designed for PCB mounting with a 5-pin configuration, ensuring stable installation on compatible boards. The switch supports single LED lighting, but it is not compatible with magnetic or capacitive features. Plate mount compatibility is unknown.

Trade-offs

The switch is not silent, so it may not suit noise-sensitive environments. It lacks tactile or click feedback, which some users prefer for typing accuracy. The force variance, while moderate, could result in slight differences between switches. Other modification potentials, such as response to additional lubing or filming, are unknown.
