The Limit Switch is designed to monitor the limit of the evaporator coil and will throw the heat on/off switch on the blower motor when it reaches its limiting temperature.

The limit switch is an electrically operated switch that opens and closes a circuit  depending on a control signal. The control signal can be produced by a thermostat, a temperature controller, an ambient temperature sensor, a preset temperature selector or a differential pressure controller. When the control signal exceeds or falls below a predetermined point, the limit switch opens or closes the associated circuit.
