KTT Hyacinth Linear Switches

Hyacinth

BrandKTT
CategoryLinear

While using a familiar combo of materials, the Hyacinth switches stand out for its design choice of a 3.5mm travel distance. This design decision was made to avoid the hard bottoming-out experience that's common with switches with longer stems; a decision driven by a commitment to create an ideal balance between tactile feedback, auditory experience, and user comfort. Moreover, the KTT Hyacinth deviates from the mainstream trend of using dual-stage elongated springs, instead opting for a single-stage elongated spring. This choice was driven by a preference for a more consistent force curve.

The technical data of a switch can be hard to understand. Our goal here is to demystify how these specs affect feel and sound. We hope this helps you discover whether or not a switch might be a good fit.

Actuation: 45g

A switch's actuation force, or force required to trigger a keystroke, on the KTT Hyacinth requires 45g of force. This is lighter than 77% of other switches' actuation force in our selection.

A switch's actuation force is based on the entire switch design.

Bottom-out: 56g

Bottoming out, or pressing all the way down, on this KTT Hyacinth switch requires 56g of force. With a lighter bottom-out than 63% of switches in our selection, the KTT Hyacinth is considered medium-light.

A switch's bottom-out force is dependent solely on its spring weight.

What matters more: Actuation or Bottom-out Force?

If you prefer to bottom-out when you type, bottom-out force is the more relevant measurement. If you do not, then actuation force is more relevant.

Factory Lubed

The KTT Hyacinth is factory lubed. This is done to reduce friction and improve the feel of the switch. Other effects include reduced noise and if a tactile switch, slightly decreased tactility. Choosing a factory lubed switch saves you time and energy from having to lube the switch yourself. Factories have drastically improved the lubing process over the years, meaning more and more factory-lubed switches are great to use out-of-the-box.

Top Housing: Polycarbonate

Polycarbonate is the KTT Hyacinth's top housing material. The use of polycarbonate in housings creates a sharper, higher-pitched, and crisper sound profile. In part, this is because polycarbonate is a relatively stiffer plastic, which leads to a more clear and resonant sound profile. Aesthetically speaking, if a switch features a clear housing, it is more likely than not to be polycarbonate. Therefore, due to its translucency, polycarbonate is especially useful to have in the top housing of a switch if you plan to use RGB lighting.

Bottom Housing: Nylon

Nylon is the KTT Hyacinth's bottom housing material. Nylon is a classic switch housing material. Typing on switches that use nylon elicits a deeper and fuller sound profile. In part, this is because nylon is a relatively softer plastic and absorbs more sound than harder plastics, thereby creating a duller and rounder sound.

A note on housings

The KTT Hyacinth uses different materials in its top and bottom housings. As such, the qualities each housing material brings to the switch will be split between the bottom and the top of the switch.

When you press down on this switch you will feel the qualities of the bottom housing: the bottom housing has more of an impact on the bottom-out sound and feel. On the other hand, the top housing will have more of an impact on the sound when you let go of a key.

Mount type: PCB (5-pin)

The KTT Hyacinth is a PCB (5-pin) mount switch. PCB-mount, or 5-pin, switches feature 2 extra alignment pins when compared to their 3-pin counterparts. This ensures alignment (i.e. switch won't rotate and will stay in place) if your keyboard does not feature a plate or if you choose not to use one. If your keyboard's PCB does not have holes for these alignment pins, you will need to trim them off before installing them.

Stem construction: Standard

The cross-shaped stem construction is the most standard as well as the most classic, as it is derived from the original Cherry switches.

Descriptors

#silky

A silky switch refers to a switch that offers an exceptionally smooth typing experience. These switches enhance the overall smoothness of the typing feel and minimze resistance when pressing and releasing keys.

#neutral

A neutral switch has a moderate actuation force requirement and a moderate sound profile. This makes the switch suitable for most intents and purposes: whether or not you are a beginner or advanced, or if you are planning to use these at home or work.

#subtle

A subtle switch has a gentle resistance which is not feather but still maintains a light typing feel. Moreover, the sound signature will not be resonant, meaning it is suitable for shared spaces.
