HMX Blush Charm SP Switches

The HMX Blush Charm SP is a linear Hall Effect switch designed for users with compatible Hall Effect keyboards seeking a smooth, light keypress with a unique aesthetic. It suits typists or gamers who prefer consistent linear feedback without tactile bumps. Its magnetic actuation system requires specific HE PCBs, limiting compatibility to select keyboards. The switch offers a soft pink design with collectible light guides, appealing to enthusiasts valuing both function and style.

Feel & Sound

The switch delivers a smooth, linear keystroke with factory lubrication reducing friction for consistent travel. It has a light operating force, making it easy to press without fatigue. The sound profile is described as a classic “mahjong” tone, which is distinct but not loud. Bottoming out is soft due to the spring and housing materials, reducing harsh impact noise.

Actuation Characteristics

It uses a 20 mm spring providing a light 36 ± 5gf actuation force and 46 ± 5gf bottom-out force. Total travel is around 3.35 mm, offering a standard key travel distance. The magnetic Hall Effect mechanism replaces traditional metal leaf contact, potentially increasing durability and reducing contact wear. Users should confirm their keyboard supports this magnetic format before considering this switch.

Build Quality

The switch features a POM stem with PC top housing and P2 bottom housing, materials chosen for smoothness and durability. Factory lubrication enhances smoothness from the start, reducing the need for immediate modifications. The included light guides add a visual element but do not affect performance.

Compatibility & Limitations

This switch is only compatible with Hall Effect keyboards and PCBs designed for HMX-style magnetic switches. It is not compatible with standard MX mount keyboards. The unique magnetic actuation means it cannot be used in most common mechanical keyboards. This limits its use to specialized setups. Unknown if hot-swap friendly. LED compatibility is not specified.
