MK Purple Slush Linear Switches

The MK Purple Slush Linear Frozen Llama is a smooth, linear mechanical switch suited for users who prefer a consistent keystroke without tactile bumps or clicks. It fits well for gamers or typists seeking a straightforward, quiet typing experience with moderate actuation force. It is less ideal for those wanting tactile feedback or silent operation.

Feel & Sound

This switch offers a linear feel, providing a smooth keypress from top to bottom without tactile or audible feedback. The sound profile is similar to classic nylon switches, producing a moderate typing noise without clickiness. Some users note a slight spring ping, which can be reduced with hand lubrication.

Actuation Characteristics

The switch actuates at a moderate force level, requiring deliberate keypresses that help prevent accidental inputs. The total travel distance is standard, with a clear bottom-out feel that some may find satisfying for typing or gaming.

Build Quality

It features a nylon top and bottom housing with a POM stem, which contributes to its smooth keystroke and durability. The spring is nickel plated, which can affect the switch’s sound and longevity. However, some users report quality issues over time, including double-clicking and key registration problems after extended use.

Compatibility & Installation

The switch uses a 5-pin PCB mount design, making it compatible with most standard mechanical keyboard PCBs. It requires soldering and is not hot-swap friendly. Bent pins on arrival have been reported, so careful handling is advised during installation.

Modification Potential

Factory lubrication is minimal, but adding hand lube can improve smoothness and reduce spring noise. Switch films do not significantly affect performance, so they are not necessary for this model.

Trade-offs

While the switch delivers a consistent linear feel, some users experience durability issues such as double-clicking and key chatter after about a year. The keycap fitment may feel loose compared to other linear switches like Cherry Reds. Bent pins on delivery can complicate installation. These factors may affect long-term reliability.
