SYMPTOM:

Repeating Characters...like "Characterrrrsssssss".

TEST:

Look for repeating characters in text editor. Doublecheck on another computer to eliminate SW (key repeat rate) issues.

CAUSE:

Switch chattering happens with all Cherry MX switches. Cause varies: Metal fatigue, contamination (often reported after liquid spill, misalignment of the metal leaf, dust.

FIX:

1. Try Compressed air to clear out possible dust (not Elitekeyboards approved!)
2. Use Deoxit to clean contacts
3. Disassemble the switch and try cleaning contacts or even GENTLY rebending them.
4. If it continues to chatter replace the switch (see buying links in the wiki)
