Jerrzi Low Profile Red Linear Switches

This linear low profile switch suits users who want a smooth, consistent keystroke with a shorter travel distance. It fits well for those using low profile keyboards compatible with MX-style keycaps and PCBs. It is a practical choice for typists and gamers who prefer a light actuation force and a streamlined typing experience without tactile feedback.

Feel & Sound

The switch offers a smooth, linear feel without tactile bumps or clicks. It produces a quieter sound profile typical of linear switches, making it suitable for shared or quiet environments. The bottom-out force provides a firm end to each keypress, which some users may find satisfying, while others may prefer a softer landing.

Actuation Characteristics

With a total travel of 3.2mm and a short pre-travel of 1.2mm, it enables quick key registration and faster typing or gaming response. The operating force of 40g is light enough to reduce finger fatigue during extended use, while the 58g bottom-out force ensures deliberate keypresses.

Compatibility

The switch uses a 5-pin design but allows clipping two pins to fit 3-pin hot-swap or soldered PCBs. It is MX compatible, supporting popular keycap sets like GMK and Vividkey. It is designed specifically for low profile keyboard PCBs, so it may not fit standard height boards.

Modification Potential

It comes unlubricated from the factory, but lubrication is generally unnecessary due to its smooth operation. Users seeking to customize sound or feel can still apply lube or films, though benefits may be minimal.

Trade-offs

The switch’s low profile design limits compatibility to certain keyboards. It lacks tactile feedback, which may be less ideal for users who prefer noticeable keypress confirmation. Unknown factors include long-term durability and spring noise, as these are not specified.
