Will it work in my grinder. I've taken it apart and ruled everything out but the switch. It's intermittent. Works sometimes. Sometimes not. Less each time.

Hi Brett,
Thank you for your question. Before we can verify if this switch will work on your grinder, we will need the complete model number from it. The DeWalt model number is usually found on a black label with the word warning on it. The model number will be found in the upper left corner with the type number listed underneath. If you could resubmit your question with this information, we would be happy to help you. We are open 7 days a week. We look forward to hearing from you!
