HMX Caramel Pudding Linear Switches

The HMX Caramel switch is a linear mechanical switch designed for users seeking a smooth keystroke with moderate resistance and a quieter sound profile compared to typical UPE-based switches. It suits typists and gamers who prefer a consistent, non-tactile feel with a slightly muted, less sharp sound. Its durability and factory lubrication make it a practical choice for those wanting a reliable, low-maintenance switch.

Feel & Sound

• Linear and smooth keystroke with no tactile bump or click.
• Operating force provides moderate resistance, balancing speed and feedback.
• Sound is deeper and thockier than other HMX switches but less so than well-known deep-sounding switches like the Vertex V1.
• Not as soft or as prone to stem breakage as traditional UPE stems, offering a firmer feel and longer lifespan.

Build Quality

• Uses a modified UPE stem designed for increased strength and durability compared to standard UPE.
• Top housing made from PA12 and bottom housing from PA66, materials chosen to enhance sound depth and durability.
• Equipped with a 22mm single-stage spring contributing to consistent force throughout the keystroke.
• Factory lubed with a mix of GPL105 and GPL205 on key friction points, reducing scratchiness and improving smoothness.

Actuation Characteristics

• Pre-travel of 2.0mm and total travel around 3.6mm provide a standard keypress distance suitable for various typing styles.
• Bottom-out force slightly higher than actuation force, offering a noticeable but not harsh bottoming feel.

Trade-offs

• Sound profile is only relatively deep within the HMX lineup, so users seeking very deep or thocky sounds may find it lacking.
• Less soft than traditional UPE stems, which may feel less cushioned to some users.
• Unknown compatibility details such as hot-swap friendliness or LED support.
