Kailh Choc V1 vs V2: Switch and Keycap Compatibility Guide
Kailh Choc V1 vs V2: Which low-profile mechanical keyboard switches should you choose? While both are designed for compact keyboards, their switch dimensions, mounting systems and keycap compatibility can differ by model. This guide explains the key differences between Choc V1 and Choc V2 switches, how to check Choc keycap compatibility, and what to consider before buying replacement switches or low-profile keycaps.
1. Key Differences
| Feature | Choc V1 | Choc V2 |
|---|---|---|
| Keycap mount | Choc V1-style mount | MX-style cross stem on supported models |
| PCB | Requires a compatible PCB | Requires a compatible PCB |
| Plate | Must match the switch design | Must match the switch design |
| Keycaps | Choc V1-compatible keycaps | Compatible MX-stem keycaps may work |
Always check your keyboard's specifications before choosing replacement switches or keycaps.
2. Typing Feel and Sound
Both versions are available in different switch types, depending on the specific model.
- Linear: Smooth keystrokes without a tactile bump.
- Tactile: Noticeable feedback while typing.
- Clicky: Audible click and tactile feedback.
Sound and typing feel also depend on the case, plate, keycaps and keyboard construction. Neither version is automatically quieter or better than the other.
3. Keycap Compatibility
Choc V1 and V2 use different keycap mounting designs.
- Choc V1: Requires keycaps designed for the Choc V1 mount.
- Choc V2: Uses an MX-style cross stem on supported models, but keycap height and clearance still matter.
A keycap that fits the stem may not necessarily fit the keyboard properly. Check the keycap dimensions and profile before ordering.
4. PCB and Plate Compatibility
Switches must match the PCB footprint, electrical contacts and plate cutouts.
A hot-swappable PCB does not support every low-profile switch. Before replacing switches, confirm the supported switch version and mounting specifications with the keyboard manufacturer.
5. Which Should You Choose?
- Gaming: Choose a switch type that matches your preference for smooth or tactile keystrokes.
- Office work: Consider typing comfort and noise level.
- Portable keyboards: Check the complete keyboard's thickness, weight and keycap height.
Your keyboard's design and the specific switch model matter more than the version number alone.
6. Pre-Purchase Checklist
Before ordering, confirm:
- Switch version: Choc V1 or V2.
- PCB and plate compatibility.
- Keycap stem type and dimensions.

8. FAQ
Are Choc V1 and V2 interchangeable?
Not by default. Check the PCB, plate and keycap specifications for your keyboard.
Can I use Choc V1 keycaps on Choc V2 switches?
Do not assume they will fit. Their keycap mounts differ.
Will all MX keycaps fit Choc V2?
Not necessarily. Keycap height, profile and clearance may affect compatibility.
Does hot-swap mean all switches are supported?
No. The PCB must support the specific switch footprint and contact arrangement.
Final Thoughts
Kailh Choc V1 and V2 offer different options for low-profile keyboard builds. Before purchasing, make sure your switches, PCB, plate and keycaps are compatible.
If you're unsure, check the product specifications or contact the manufacturer before ordering.
