Gateron KS-9 Silent 2.0 Yellow Linear Switches — 10PCS at a Glance

Factory Lubed
50 gf
Operating force
Medium 50gf linear force with quieter impact
The Yellow version has 50±15gf operating force; the other Yellow, Red, Black and White versions do not all use the same spring rating. Factory pre-lubrication and top/bottom silencing pads are designed to smooth travel and reduce hard keypress impact noise, not to produce total silence or guaranteed dB reductions.
Performance, sound and lube uniformity are not KeebPilot laboratory measurements; any community experiences are subjective and build-dependent.

Should you choose these switches?
Users seeking a medium-force, dampened linear switch for a shared desk or late-night keyboard.
- Yellow variant buyers who want 50gf rather than confusing it with another color.
- Owners of compatible MX mechanical boards seeking a 10-switch tryout or replacement pack.
Silent dampeners change the bottom-out feel; some typists prefer the firmer impact of non-silent switches.
- Not soundproof: stabilizers, keycaps and the board can still produce noise.
- 5-pin does not universally fit every 3-pin-only PCB or proprietary socket.
Choose your options
Before you buy: check the switch socket
These are conventional MX-style mechanical-contact switches. Check socket technology and your PCB/plate mounting arrangement; Hall Effect and optical-only boards are not compatible.
Mechanical socket
Confirm a standard MX-style mechanical switch interface; magnetic Hall Effect and optical-only sockets are different technologies.
Mounting
Gateron lists KS-9 Silent 2.0 as 5-pin, factory-pre-lubed switches compatible with MX mechanical sockets that accept five locating/contact legs. Verify compatibility for your keyboard, especially older 3-pin-only sockets.
Keycaps and lightingCheck MX stem fit, your LED position and keycap lighting requirements; lighting appearance is not guaranteed.
Check your actual PCB, plate and keyboard layout before buying.
How many switches should you order?
Choose your keyboard layout to get a practical starting quantity. Then confirm the exact key count for your board and decide how many spare switches you want for testing or replacement.

FAQ
How much force does Silent Yellow use?
Gateron lists the Yellow model at 50±15gf operating force.
Is it truly silent?
It includes dampening pads designed to reduce stem impact noise, but actual keyboards still make some sound.
Will it fit a magnetic or optical keyboard?
No. It is an MX-style mechanical switch, not Hall Effect or optical.
Are these 3-pin or 5-pin?
Official KS-9 Silent 2.0 uses a 5-pin design. Check the PCB before purchase.
How many switches are shipped?
10 switches of the selected color. 35PCS is a separate sourced option and must not be assumed included.
