The KSD5012 defrosting thermostats Automatic Reset SPST adnd SPDT.The switch can be built to either open or close its electrical contacts on temperature rise. Once the temperature in the application has returned to the specified reset temperature, the contacts will automatically return to their original state, including limiting and regulating temperatures in air conditioners,heat pumps and fan coil units This design is the same as the SPST described above with the addition of an auxiliary contact which makes circuit upon opening of the main contacts and breaks circuit when the  auxiliary contacts. Typical uses of this construction include fan speed changeover at a specified temperature and lighting of an indicator lamp when an abnormal temperature conditionhas been reached.
