TEMCo Float Switch for Sump Pump & Water Level Empty Function Control 13ft Cord 5 Year Warranty CN0360

 PartNumber: CN0360   |   Asin: B07DX96VFH

TEMCo Industrial's float switches feature high quality German-manufactured Cherry switches inside a robust IP68 enclosure. That means whether you need to drain a basement or fill a container, we've got you covered. Not sure what type of control function you need? Check out our handy guide in the Image Gallery Above.

The switches come pre-wired to a standard American plug (NEMA 5-15P to NEMA 5-15R). That means you can plug the switch in, plug your control device directly on top, and you're ready to go. No soldering, no color-coded wiring, no fuss - just plug it in.

These float switches are rounded so that they don't get caught up on any floating *ahem* solids. They also have short actuation lengths, which means you have reliable switching no matter how much slack you give the switch. Our float switches come equipped with a generous 13 foot cord, which also has an IP68 rating.these switches also come equipped with a 1 year no-questions-asked return policy and a 5 year warranty against manufacturing defects. That means you're about to purchase a high quality switch backed by high quality customer service.
