About the Mars 39055

Savings available on the Mars 39055 L130-2 Limit Switch here at PlumbersStock.com. 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 a reputable heating and cooling manufacturer and we are so proud to carry their products.
