Setup and Installation
The Cherry MX2a Purple Switches are 5-pin switches, compatible with most hot-swappable mechanical keyboard PCBs that support 5-pin switches. For soldered PCBs, ensure proper alignment before soldering.
Installation Steps:
- Preparation: Ensure your keyboard PCB is clean and free of debris. If replacing existing switches, carefully remove them using a switch puller.
- Alignment: Align the two metal pins and the central plastic pin of the Cherry MX2a switch with the corresponding holes on the PCB. The two smaller plastic alignment pins should also fit into their respective holes.
- Insertion: Gently press the switch into the PCB until it clicks into place. Ensure the switch is fully seated and flush with the PCB. Do not force the switch, as this may bend the pins.
- Verification: After installing all switches, test each key to ensure it registers correctly. If a key does not register, carefully remove the switch, check for bent pins, straighten them if necessary, and reinsert.

Operating Characteristics
The Cherry MX2a Purple Switch is a tactile switch, meaning it provides a noticeable bump during actuation, offering feedback to the user without a loud click. This makes it suitable for both typing and gaming where tactile feedback is preferred.
- Tactile Feedback: A distinct bump is felt as the key is pressed, indicating actuation.
- Actuation Force: The force required to register a keypress is optimized for a balanced typing experience.
- Factory Lubed: These switches come pre-lubricated from the factory, ensuring smooth operation and reducing spring ping or scratchiness.
- 5-Pin Design: Provides enhanced stability when mounted on a PCB.
Maintenance
Proper maintenance can extend the lifespan and maintain the performance of your Cherry MX2a Purple Switches.
Cleaning:
- Dust Removal: Regularly use compressed air to blow away dust and debris from around and under the keycaps.
- Keycap Cleaning: Remove keycaps and clean them with a mild soap solution and water. Ensure they are completely dry before reattaching.
- Switch Cleaning: For deeper cleaning, switches can be carefully removed from hot-swappable PCBs. Use a soft brush or cotton swab with isopropyl alcohol to clean the exterior of the switch housing. Avoid getting liquid inside the switch.
Lubrication (Optional):
While these switches are factory lubed, some users may prefer to re-lube them for a customized feel. This process involves disassembling the switch and applying a thin layer of specialized switch lubricant to the stem, spring, and housing rails. This advanced maintenance should only be performed by experienced users.
Troubleshooting
Here are some common issues and their potential solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Key not registering | Bent switch pins, switch not fully seated, faulty PCB socket. | Remove switch, straighten pins carefully, reinsert. Ensure switch is fully pushed in. Test with another switch to rule out PCB issue. |
| Inconsistent feel/scratchiness | Insufficient lubrication, dust/debris inside switch. | Clean around the switch with compressed air. Consider re-lubricating the switch if comfortable with disassembly. |
| Switch feels stuck/sluggish | Excessive dust/debris, foreign object. | Remove keycap and inspect for obstructions. Use compressed air to clear. |
