Input Gear KEEBFRONT Coley Linear Switches

The Input Gear KEEBFRONT Coley is a linear mechanical switch designed for custom keyboard enthusiasts seeking a smooth and fast typing experience. It suits users who prefer consistent keypresses without tactile bumps or clicks. Its construction focuses on stem stability and minimal internal play, aiming for precise and clean keystrokes.

Feel & Sound

This switch offers a linear feel, meaning keypresses are smooth from top to bottom without tactile feedback or audible clicks. The stem’s extended length improves guidance, reducing wobble and contributing to a more stable typing sensation. Sound profile is expected to be quiet with a clean bottom-out, but exact noise characteristics are unknown.

Actuation Characteristics

The actuation force is moderate, requiring about 63.5 grams to bottom out, which balances speed and control. Pre-travel and total travel distances are not explicitly specified, but the pre-travel is likely around 2.0 mm, typical for linear switches. The bottom-out feel is solid due to the sturdy housing design, which limits unwanted movement.

Build Quality

The switch uses a POM stem, known for smooth sliding properties. The top housing is made of Nylon PA6 and the bottom housing of PBT, materials chosen for durability and reduced friction. The robust housing setup minimizes stem wobble and internal looseness, enhancing consistency over time. It ships unlubed, so users may want to apply lubricant to reduce scratchiness and noise.

Compatibility & Modification

It features a PCB-mount design with a 5-pin MX footprint, compatible with most custom keyboards using standard MX-style sockets. The unlubed factory condition allows for user customization through lubing or filming, which can further improve smoothness and sound. Hot-swap compatibility is unknown.

Trade-offs

Without factory lubrication, initial scratchiness or noise may be noticeable until broken in or lubricated. The lack of tactile feedback makes it less suitable for users who prefer a bump or click. Pre-travel and total travel details are not confirmed, which may affect precise actuation expectations.
