Modular Flexibility: Part of the System 350 family

Technicians should look for open circuits during a continuity test

meaning it restores continuity once the internal temperature drops back to a safe operating level

ensuring the magnetic field strength is sufficient to shift the valve spool even under high differential pressures

Consistent Flow Rate: Prevents ink blotches or skips

Williams P296001 Limit Switch 321042-401 Modular Flexibility: Part of theThe Williams P296001 Limit Switch is a critical safety component designed for Williams Forsaire Top Vent (5008 Series) and Direct Vent (5507 Series) wall furnaces. This L175 35F limit switch serves as a high limit safety control, engineered to break the electrical circuit to the burner or blower if internal temperatures exceed the 175F safety threshold. Functioning with a normally closed (NC) contact configuration, it features an auto reset mechanism
