Index HVAC Blower Motor Switch

There’s more to temperature regulation than fans and thermostats. The Index HVAC Blower Motor Switch responds to thermal changes within HVAC systems by activating or deactivating components once a specific threshold is met. This unit is set to operate at 205°F and features a normally open (NO) contact, which closes once the temperature hits that level. It’s commonly used in heavy-duty applications where passive cooling is insufficient and additional systems must be triggered to protect engine or HVAC performance. When overheating becomes a consistent issue, the Index 8037034P can help.
