MMD Princess Shaft: A linear mechanical keyboard switch with selectable pressure and extended spring
For mechanical keyboard builders and modifiers seeking granular control, the MMD Princess Shaft provides a linear switch option defined by its specifications. This switch eschews vague marketing terms in favour of concrete data: trigger pressure, bottom pressure, travel distance, and spring dimensions. It is designed as a component for those who understand that the feel of a keyboard is dictated by these measurable factors. The core appeal lies in the ability to select a specific activation weight, supported by a long 20.4mm spring, to create a keystroke profile that matches your exact preference for typing or gaming. This product is a single switch body, acknowledging that customisation often happens one key at a time.
Features and Construction
The MMD Princess Shaft is defined by its linear operation and its detailed, user-selectable specifications. Unlike tactile or clicky switches, a linear axis offers a smooth press from top to bottom without a pronounced bump, which some users prefer for gaming or quiet, consistent typing. The construction is focused on delivering a specific pressure curve, starting with the choice of trigger force.
Material and Build
The switch is built as a complete mechanical keyboard shaft body. Its operation relies on the precise interaction of its internal components, including the metal spring and the plastic slider mechanism. The spring is a central part of its design, specified as an extended 20.4mm length spring made from wire with a 0.23mm diameter. This spring dimension directly influences the force curve, contributing to the switch's feel from initial press to bottoming out.
Size and Practical Fit
The switch conforms to standard mechanical keyboard switch footprints, designed to be soldered or hot-swapped into a compatible PCB. Its operational dimensions are clearly stated: a total travel of 3.6mm, with the actuation point occurring at 2.0mm of that travel. These figures are crucial for understanding the key's depth of press and when the electrical signal will be sent. The physical size ensures compatibility with most custom keyboard kits and aftermarket keycap sets that support the standard MX-style stem.
Uses and Placement
This switch is a component for creating or modifying a personal input device. Its value is realised when installed into a keyboard, where its specifications translate directly to the user's daily interaction with their computer.
Event or Professional Use
For gaming marathons or long coding sessions, the consistent, bump-free travel of a linear switch can reduce finger fatigue. The ability to select a heavier 55gf or 60gf trigger pressure can provide more resistance against accidental key presses during tense moments, while a lighter 38gf option might suit rapid, repetitive keystrokes. The defined 2.0mm actuation point offers a reliable and predictable response time, which can be beneficial for rhythm games or any application where timing is critical.
Everyday Home Use
In a home office or general use setting, the MMD Princess Shaft allows you to tailor the keyboard's typing feel to your personal comfort. A lighter spring variant can make typing feel effortless, while the smooth linear motion can be quieter than tactile switches, especially when paired with appropriate keycaps and modding. Building a board with this switch turns an everyday tool into a personalised one, where every key press feels exactly as you intended.
Benefits and Buying Value
The value of this product lies in its specificity and its role as a fundamental building block for a custom keyboard. It provides control over an aspect of computing that is often taken for granted.
Reuse and Low Maintenance
As a mechanical switch, it is designed for long-term use and can be de-soldered and reused in different keyboard builds if needed. Its performance is based on its physical construction rather than software, meaning it will maintain its feel over time barring physical damage. The simplicity of the component means there is no firmware to update or drivers to install.
Why Choose This Product
Choose the MMD Princess Shaft if you require a linear switch with clearly documented specifications and a choice of trigger pressures. It is for the user who moves beyond generic 'red' or 'black' switch labels and wants to engage with the actual gram-force measurements and spring design. The inclusion of both 'Artificial Run' and 'Factory Run' options for each weight provides an additional layer of choice, potentially offering slight variances in manufacturing or tuning for the discerning enthusiast. It represents a move from buying a pre-built keyboard to constructing a tool that matches your precise physical requirements.
