Input Gear M1 Z2 Linear Switches

The Input Gear M1 Z2 is a linear mechanical switch suited for users seeking a smooth, consistent keystroke without tactile feedback. It fits well for typists and gamers who prefer a straightforward, quiet keypress with a moderate actuation force. Its design supports Cherry MX-compatible keyboards, making it a flexible choice for custom builds or replacements.

Feel & Sound

This switch offers a smooth, linear feel with no tactile bump, resulting in a consistent keystroke from top to bottom. Factory lubrication reduces scratchiness, contributing to a quieter and more fluid typing experience. The sound profile is relatively muted compared to tactile or clicky switches, suitable for office or shared environments.

Actuation Characteristics

The switch actuates with moderate force, providing a balance between responsiveness and fatigue prevention during long typing sessions. A pre-travel distance of 2.0 mm and total travel of 3.6 mm deliver a quick reset and a lively typing rhythm. Bottoming out requires slightly more force, which can help avoid accidental key presses.

Build Quality

It features a LY stem combined with a polycarbonate top housing and nylon bottom housing, materials known for durability and stable performance. The 22 mm dual-stage spring design supports a fast return and consistent force curve. Factory lubrication is applied to enhance smoothness and reduce initial break-in time.

Compatibility

The switch uses a 5-pin PCB mount compatible with most Cherry MX-style keyboards. This ensures broad compatibility with custom and standard mechanical keyboard PCBs. LED compatibility and hot-swap friendliness are unknown.

Trade-offs

While factory lubrication improves smoothness, additional lubing or filming may still be needed for users seeking ultra-silent or ultra-smooth operation. The linear design lacks tactile feedback, which some typists may find less satisfying. Unknown factors include spring ping or stem wobble, so some break-in or personal adjustment might be necessary.
