How does the high limit switch on a hot tub work?

Your high limit switch measures the water temperature by either a capillary tube attached to a bulb or a mounted sensor. If the switch detects unsafe temperatures, it opens to break the circuit and keep the heater from literally melting down. Once the water temperature in the hot tub has decreased, the high limit switch must be reset manually.
