Features & Applications

The Poly Switch devices are the world's leading resettable PPTC (polymeric positive temperature coefficient) devices for over current protection in a broad variety of electronic equipment applications. So much more than a simple fuse alternative, resettable circuit protection is an important aspect of product reliability and safety.

This helps to prevent costly damage to printed circuit boards, guard against damage caused by unsafe battery charging conditions, protect motors from failure and in many other ways and increases the value of your products and systems.
