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.
A switch's actuation force, or force required to trigger a keystroke, on the KTT Hyacinth requires 45g of force. This is lighter than 75% of other switches' actuation force in our selection.
A switch's actuation force is based on the entire switch design.
Bottoming out, or pressing all the way down, on this KTT Hyacinth switch requires 56g of force. With a lighter bottom-out than 62% 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.
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.
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.
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.
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.

Try KTT Hyacinth switches before buying them
Pick 10 switches and we'll send them your way to try at home for 5 days.
How it works
First, pick 10 switches you want to try. Then, we'll send you those 10 switches to try at home for 5 days. You'll get to experience the switches and see how they feel. We'll also include a guide to help you pick your favorite switch and a preprinted return shipping label.
What comes in my try at-home box?
The 10 switches you choose will be installed on switch tester bases so you can type on them as you would on a normal keyboard. Your try at-home kit comes with a preprinted return shipping label.
How much does this try-before-you-buy program cost?
At just $10—shipping included—the try at-home program is the most cost-effective way to try switches before buying them. At less than half the cost of switch testers and with more than triple the variety to choose from, you can try before you buy without breaking the bank so you can be sure you're getting the right switch for your needs.
How do I buy the switches I want?
Send back the switches in your box using your prepaid label and purchase your favorite (or favorites)!
Everything that's included
First, try switches at home with shipping included both ways. After purchasing the switches you love most, know your switches come with a 30-day, hassle-free return or exchange policy. If you don't love your switches, we'll take them back—no questions asked.
