Carrier HH18HB033 Temperature Switch

The Carrier HH18HB033 Temperature Switch is a component that is installed in HVAC equipment to control temperature. This enables electrical circuits to be switched ON or OFF depending on a desired temperature range. When the temperature is within the set point the switch opens the relay and breaks the circuit to switch off the heating or cooling system. When the temperature goes below the set limit, the switch breaks the circuit and the heater or cooler turns on again. This sequencing or switching relay type provides better temperature control of HVAC units. Temperature Switch is compact which makes it appropriate for use in different HVAC equipment.
