Oshkosh Thermostatic Control Switch

Oshkosh Thermostatic Control Switch

This is a thermostatic control switch used to regulate the temperature of the heater system inside the cab of a heavy-duty truck. The switch operates using a 21-inch capillary tube that senses the air temperature and cycles the heating system to maintain the desired setting. It is a crucial component for maintaining a comfortable operating environment for the driver during cold weather. This part is a direct replacement for specific OEM switches used in various truck models, including certain Kenworth series, but is utilized in Oshkosh front discharge mixer applications.
