This is a BRAND NEW 180 degree 1 Pole Limit Switch (L180) with a Manual Reset Button! Look at your fan switch and you should find the temperature rating of yours listed on the switch itself! The Coleman part # on this switch is 7624A3591 (also 7624-A359) but this part number has replaced many other Coleman part numbers for 180 degree Manual Reset Limit Switches! Thanks for looking and good luck!
A limit switch is a safety device designed to shut down a piece of equipment. Limits have a set point, which is in some cases, adjustable. The set point prevents the temperature or pressure from exceeding the rating of the switch.
