Solid-state PolySwitch® PPTC bladed devices are resettable fuses. They act like resistors, lowering the flow of current as they heat up in response to an overcurrent. Once the overcurrent abates and the temperature of the PolySwitch fuse lowers, current resumes flowing. The small size and high reliability of these bladed resettable fuses make them ideal for protecting thin wires connected to micro motors for power windows, power mirrors, sunroofs and seat controls where fuse boxes are impractical.
