Geon Lucifer HE Linear Switches

The Geon Lucifer Magnetic HE is a linear hall effect switch suited for users seeking analog input with smooth keypresses. It fits keyboards compatible with the Gateron KS-20 footprint, including Venom HE PCBs. This switch is a good option for those interested in hall effect technology at a lower cost, offering a consistent linear feel without tactile bumps or clicks.

Actuation Characteristics

The switch provides an analog pre-travel range from 0.1 to 3.7mm, allowing variable input detection before full travel. Total travel is 3.8mm with a bottom-out force of 45g, which delivers a moderate resistance that is neither too light nor heavy. The linear force curve supports smooth keypresses without tactile feedback, making it suitable for users who prefer fluid motion and analog control.

Feel & Sound

With a linear design and POM stem, the switch offers a smooth keystroke experience. The bottom-out feel is relatively soft due to the 45g force, reducing finger fatigue during extended typing or gaming sessions. The sound profile is expected to be quiet and muted, though exact noise levels are unknown. The hall effect mechanism eliminates physical contact wear, potentially enhancing durability and consistency over time.

Build Quality

The switch uses a polycarbonate top housing and nylon bottom housing, which balance durability and weight. The POM stem reduces friction for smoother keypresses. It includes a single-stage spring and is factory lubed, which can improve smoothness and reduce scratchiness, a common issue where the stem rubs against the housing. The 2-pin design fits standard PCB mounts but may limit hot-swap compatibility on some boards.

Compatibility

Designed for keyboards supporting the Gateron KS-20 footprint, it works natively with Venom HE PCBs. The 2-pin mount is common but may not fit all hot-swap sockets, so users should verify compatibility with their keyboard. LED compatibility is unknown. The hall effect sensor requires a compatible PCB to register analog input, limiting use to supported boards.

Trade-offs

The analog input range offers flexibility but may require software support to fully utilize. The 2-pin mount restricts compatibility compared to more common 3-pin or hot-swap designs. While factory lube improves smoothness, additional lubing may still be needed for optimal feel. The switch lacks tactile or click feedback, which may be less ideal for users who prefer more pronounced typing sensations.
