The switch on a belt sander endures constant use, and eventually, it will fail. Often, this happens without any prior warning. In fact, one of the most common (and frustrating) symptoms of a faulty switch is that the sander works perfectly one minute, and then fails to work at all the next time you activate the switch. Fortunately, replacing the switch in a belt sander is easy to do, especially when you follow our step-by-step instructions. If you're ready to make the switch, this article will show you how.

Use a crimping tool to crimp the eyelet and secure the connection.
Repeat this step to install the second eyelet onto the remaining black wire.
5. Connect the new switch.
