How to Replace the Switch on a Porter Cable Belt Sander Model 352VS

How to replace the switch on a Porter Cable belt sander The Facts

If raised grains and elbow strains are sanding away your patience, it's time to face the fix. Whether you are a sanding pro or a seasonal sander, eReplacementParts.com provides the parts, procedures and facts you need to fearlessly fix what fails you.

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.
