Spa High Limit Switches

High limit switches have a reset button that pops out when tripped. This opens the switch allowing no path. If the button is not popped out you should have continuity through the poles of the high limit.

The primary job of the High Limit Switch in the finished product is to prevent scalding water from ever reaching the people using the product. Sure, the thermostat should shut the heater off long before the point at which the High Limit Switch is needed, but thermostats, like everything else, fail.
