Durock Mamba Linear Switches

The Durock Mamba Linear is a smooth linear switch suited for users who prefer consistent, uninterrupted keypresses with moderate resistance. It fits well for gamers and typists seeking a balance between light actuation and a noticeable bottom-out force. Its design supports PCB mounting and single LED compatibility, making it suitable for custom builds with standard MX-style layouts.

Feel & Sound

• Linear feel provides a smooth keystroke without tactile bumps or clicks.
• Moderate actuation force offers resistance that helps prevent accidental keypresses.
• Bottom-out force is higher than actuation, giving a firm end to each press.
• Sound profile is generally quiet with a soft thock due to polymer housing materials.

Actuation Characteristics

• Actuation occurs at 2.00mm, allowing for relatively fast input recognition.
• Total travel of 3.50mm provides a standard depth for comfortable typing.
• Force variance of 10 cN means consistent feel across keys with minor variation.

Build Quality

• Stem made from a polymer nylon and UHMWPE blend, which can reduce friction for smoother keypresses.
• Top housing is nylon, bottom housing is POM, both materials known for durability and low noise.
• Includes an extended long spring and long pole design, which may affect spring noise and feel.

Compatibility

• PCB mount design requires compatible PCBs, not plate mount.
• Supports single LED lighting, compatible with most standard backlighting setups.
• Five-pin construction improves stability on the PCB.

Trade-offs

• Linear switches lack tactile feedback, which may be less ideal for users who rely on keypress confirmation.
• Long spring and pole design could introduce spring noise or require break-in for smoothness.
• Unknown factory lubrication quality, so additional lubing may be needed to reduce scratchiness or improve smoothness.
