Input Gear Purple Potato Tactile Switches

The Input Gear Purple Potato is a tactile mechanical switch designed for users who want clear, noticeable feedback while typing. It suits enthusiasts who prefer a pronounced bump to confirm keypresses rather than a smooth or quiet experience. This switch is less ideal for those seeking linear or silent operation.

Feel & Sound

This switch offers a strong tactile bump described as large and rounded, providing distinct feedback with each keystroke. The feedback helps users feel when a key actuates, which can improve typing accuracy. It is not designed to be quiet, so expect moderate sound levels with a noticeable clicky feel rather than a muted or soft press.

Actuation Characteristics

The actuation force is relatively high, requiring deliberate keypresses that reduce accidental inputs. The total travel distance is standard, with an actuation point near the midpoint, allowing for confident key registration. The spring is extended, contributing to a firm bottom-out feel that some users may find satisfying, while others may perceive it as stiff.

Build Quality

The switch uses POM (polyoxymethylene) for both housing and stem, materials known for smoothness and durability. This construction can reduce friction, enhancing the tactile experience. It comes lightly pre-lubed from the factory, which may improve smoothness out of the box but could benefit from additional lubrication for quieter operation.

Compatibility

Featuring a 5-pin design, it is compatible with most PCB and plate mount setups, including those requiring stable mounting. Details on LED compatibility or hot-swap friendliness are unknown.

Trade-offs

The firm spring and strong tactile bump may cause finger fatigue during extended typing sessions for some users. The switch is not optimized for quiet environments due to its audible feedback. Additional modifications like lubing or filming might be necessary to reduce noise or smooth out any scratchiness, though factory lubrication is present.
