MARS 39026 Limit Switch 321142-301 this actuator is a standardThe MARS 39026 Limit Switch is a high performance L220 4 HVAC temperature control designed for precise thermal management in furnace and air handling systems. As an Open on Rise limit switch, this component is engineered to automatically interrupt the circuit when the temperature reaches the 220F (104C) cut out setpoint, ensuring system safety and preventing heat exchanger damage. Once the temperature drops to the 180F cut in threshold, the switch
