What it does:

The high limit switch monitors water temperature within the heating system. If the temperature reaches approximately 225°F, the switch changes electrical state to interrupt the burner control circuit and prevent the burner from continuing to add heat.

High Limit Switch vs. Thermostat:

An adjustable thermostat regulates the pressure washer's normal operating temperature. The high limit switch is a safety device that provides an additional cutoff when the system reaches its preset temperature limit.

Why it matters:

A properly functioning high limit switch helps protect against:

• Excessive water temperatures

• Burner overheating

• Heating coil damage

• Damage to hoses, seals, and other components

• Unsafe equipment operation

The 1/2" MPT connection, 225°F fixed temperature setting, and 42" wire lead make this high limit switch a convenient replacement for compatible commercial hot water pressure washer systems.
