About the Mars 39022Be sure to take advantage of this deal on the Mars 39022 180 Limit Switch L180-40 Auto Reset 3/4" here with the pros at PlumbersStock. Limit switches are sensors that detect when a furnace has exceeded operational temperature limits and shut the appliance down as a safety measure. The way it works is that if your temperature gets to a concerning level, the limit switch will automatically open the circuit so it shuts off. It will remain off until the switch automatically closes the circuit when the temperature reaches the off threshold. Mars is known for engineering innovation and practical solutions. |
