PB Rocker Switch, Power, for Early Polar Bear Distillers, not lighted or indicated on switch (indication of on/off on distiller)! Time will cause contacts to corrode/wear and the resistance(at the contacts and attaching connectors) will gradually increase to cause the switch to overheat and fail. Replacement is reasonably cheap and easily performed with minimal tools. Switch carries household current, if not familiar with the precautions for this kind of work, please contact Triangle for repair options!
