"SPDT MED TEMP CTRL
__The SPDT Switch with built-in Temperature control is the perfect solution for most heating and cooling projects. Easily activate the switch for either "ON" or "OFF" operation using a screwdriver or Allen wrench. With a ± 5°F Temperature control range (for heating and cooling) this easy to install and use switch will help you save time and money with ease of installation.
This useful SPDT temperature controller will accept input voltages from 9 to 32 volts DC and is designed for use with a 0 to 55°C sensor. Ideal for use in automotive, industrial, laboratory and special process applications. It will minimize temperature fluctuations through output load regulation while compensating for changes in room ambient temperature."
