Conductive Pills Manufacturers
- Elite Sales - Keypads and elastomers
- Xiamen Keyuan Electronic Industry - Great company! I contacted them, and they sent me a few thousand carbon pills for free. I just had to provide a shipping number. The pricing for 100,000 pills was $40 for 2.5mm and $60 for 5mm pucks. Sources of carbon pills are very hard to find - it's not like you can find them on digikey.
