Durock Black Linear Switches

This linear mechanical switch offers a smooth, consistent keystroke with a relatively high actuation force, making it suitable for users who prefer deliberate key presses without tactile bumps or clicks. It fits well for typists or gamers seeking a firm, linear feel and can handle extended use due to its durable construction. It is less ideal for those who want tactile feedback or quiet operation.

Feel & Sound

• Provides a smooth, linear keystroke with no tactile bump or audible click.
• Sound profile is moderate, not silent, producing a typical mechanical switch noise without added clickiness.
• Bottoming out feels firm due to the 78g actuation force, which may reduce accidental key presses.

Actuation Characteristics

• Requires a relatively high force of 78 cN to actuate, suitable for users who prefer deliberate key presses.
• Actuation occurs at 2.00 mm with a total travel of 4.00 mm, offering a standard mechanical switch distance.
• Linear force curve ensures consistent resistance throughout the keypress.

Build Quality

• Features a polycarbonate top housing and nylon bottom housing, contributing to durability and a slightly softer sound compared to harder plastics.
• Stem made of POM (polyoxymethylene) reduces friction for smoother keypresses.
• Gold-coated spring and leaf improve corrosion resistance and electrical reliability.
• Rated for 50 million operations, supporting long-term use.

Compatibility

• PCB mount with 5 pins ensures stable installation on compatible PCBs but is less flexible for hot-swap sockets designed for 3-pin switches.
• SMD LED compatible, allowing backlighting with compatible keyboards.

Trade-offs

• Higher actuation force may cause fatigue during extended typing sessions for some users.
• Not silent, so it may not suit quiet office environments.
• Unknown factory lubrication quality, which can affect smoothness and sound without additional modding.
