How to Use a CNC Aluminum Switch Opener

Quick Answer

Using a CNC aluminum switch opener is the safest way to open MX and Box-style switches for lubing, filming, or spring swapping. Align the switch correctly, press firmly, and lift the top housing straight off.

Step-by-Step Guide

1. 1. Position the Switch: Hold the switch opener in your non-dominant hand with the open slot facing up. Place the switch upside down into the slot so that the two plastic latches on the switch housing align with the opener's gripping edges. Common mistake: Inserting the switch right-side up. The latches must face the opener's prongs.
2. 2. Apply Even Pressure: Press the switch down firmly and evenly with your thumb until you hear or feel a click. The opener's prongs will push the latches inward, releasing the top housing. Checkpoint: If the switch doesn't open, rotate it 180 degrees — some openers only work in one orientation.
3. 3. Lift the Top Housing: While still holding the switch in the opener, gently lift the top housing straight up with your other hand. The stem and spring will remain in the bottom housing. Remove the stem carefully to avoid losing the spring. Common mistake: Twisting the top housing off can bend the switch pins. Always pull straight up.
4. 4. Reassemble or Store: After lubing or modding, place the stem back into the bottom housing, align the top housing, and press down until both latches snap closed. Test the switch before installing it into your keyboard plate. Checkpoint: A switch that doesn't snap back together evenly may have a misaligned spring or stem.
