Gateron CJ Dark Blue Linear Switches

This linear mechanical switch offers a smooth, consistent keypress with a moderate actuation force, suited for users who prefer a straightforward typing or gaming experience without tactile bumps or clicks. It fits well for those who want a reliable linear feel with a slightly heavier spring than typical light linear switches. It is less ideal for typists seeking tactile feedback or for environments requiring silent operation.

Feel & Sound

• Provides a smooth, linear keystroke without tactile feedback or audible click.
• Not silent, so it produces typical switch noise during use, which may be noticeable in quiet settings.
• Bottoming out feels firm due to the 50 cN actuation force and 15mm steel spring.

Actuation Characteristics

• Actuates at 2.00 mm with a total travel of 4.00 mm, offering a balanced response for both typing and gaming.
• Requires moderate force (50 cN) to actuate, which can reduce accidental key presses but may cause fatigue during long sessions for some users.
• Force variance of 15 cN indicates some variability in key feel across switches.

Build Quality

• Features a proprietary INK-blend top housing and POM bottom housing, which contribute to durability and smooth stem movement.
• The stem is made of POM, a low-friction material that supports smooth key travel.
• Equipped with a 15mm steel spring, providing consistent resistance and longevity.
• Comes unlubed, meaning initial feel may be slightly scratchy until broken in or manually lubricated.

Compatibility

• PCB mount design with 5 pins, compatible with most standard mechanical keyboard PCBs.
• Supports SMD LEDs, allowing for backlighting customization.
• Unknown if compatible with hot-swap sockets; typically requires soldering.

Trade-offs

• Unlubed factory condition may result in some scratchiness, requiring user lubrication for optimal smoothness.
• Not silent, so may not suit noise-sensitive environments.
• Moderate actuation force can be tiring for users preferring lighter switches.
