The Honeywell C437D1013 is a gas and air pressure switch designed for industrial combustion safety and control applications. It carries a pressure range of 1/2 to 5 PSIG with a maximum sustained operating pressure of 15 PSI, as indicated on the original box label. The switching configuration is single-pole single-throw (SPST), and the unit is designed to break on pressure rise, meaning the circuit opens when pressure exceeds the set point. A manual reset mechanism is required to restore the switch to its normal operating state following a trip event, which is consistent with safety shutoff applications in gas-fired industrial furnaces, ovens, and combustion systems.

The device is part of Honeywell's C437D series of gas pressure switches, produced under the Home and Building Control division and manufactured by Honeywell Inc. of Minneapolis, Minnesota. The document reference number 32007210-001 Rev. A appears on the box label. This product contains mercury in the switching element and is subject to disposal or recycling requirements per applicable local or state environmental regulations, as noted on the packaging.

The item is presented in its original Honeywell cardboard box with the manufacturer's label intact. Part number C437D1013 is the market-recognized MPN for this model as used in active US industrial listings.
