4.4 Hot-Swappable Switches
The VK66 PRO is equipped with a hot-swappable PCB, allowing you to easily replace mechanical switches without soldering. It supports both 3-pin and 5-pin switches. The keyboard comes pre-installed with POM linear switches, known for their creamy and thocky sound profile.
- To remove a keycap, use the provided keycap puller.
- To remove a switch, use the provided switch puller, gently gripping the top and bottom clips of the switch and pulling upwards.
- To install a new switch, align the pins with the holes on the PCB and press down firmly until it clicks into place. Ensure pins are straight to avoid bending.

4.5 Gasket-Mounted Design
The keyboard features a gasket-mounted structure with multiple layers of filling material between the PCB, positioning plate, and switches. This design optimizes elasticity and stability, providing a softer, more elastic typing experience and reducing rigid noise for a satisfying, low-noise sound profile.
