MPL 9370: Low Pressure Snap-Action Switch

Introduction

MPL 9370 Series switches offer pressure, vacuum and differential for sensing very low set points applications, with switching current up to 5A resistive, 2.5A inductive. Designed for use in the HVAC industry, where reliable air proving is critical to both performance and customer safety, the MPL 9370 Series is a favorite with leading manufacturers of gas-fired warm air furnaces and water heaters.

Smaller and lighter than any other HVAC pressure switch, the MPL 9370 is built for the same temperature range and operating life as conventional switches made of stamped steel.

The MPL 9370 will perform equally well in other applications which demand low OEM unit cost, robust design, set point accuracy, and high reliability.
