The Swimables Hi Limit Switch SW-41-063 is a vital safety device that monitors water temperature and automatically shuts down the heat exchanger the moment readings climb above the safe threshold of 135°F. A failed high limit switch typically triggers an HLS error code on your heater's display, signaling that immediate replacement is needed. Because this switch is a one-time-use safety component, it cannot be reset and must be swapped out with a new unit. The SW-41-063 is engineered for broad compatibility across most Pentair MasterTemp and Sta-Rite Max-E-Therm Natural Gas swimming pool heaters.

Key Benefits

• Essential Overheating Safeguard: Continuously monitors water temperature and immediately halts the heat exchanger when readings surpass the 135°F safety threshold.
• Built-In Fault Notification: Triggers an HLS error code on the heater display to alert you that the switch has tripped and a replacement is required.
• Single-Use Safety Design: Engineered as a non-resettable device that must be replaced after activation, ensuring fail-safe protection every time.
• Extensive Heater Compatibility: Fits a wide array of Pentair units, including MasterTemp, Sta-Rite Max-E-Therm, and ETI 400 Natural Gas pool heater models.
