MPL 9300 Series switches offer pressure, vacuum, and differential models capable of sensing very low setpoints, and 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 9300 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 9300 is built for the same temperature range and operating life as conventional switches made of stamped steel. MPL 9300 will perform equally well in other applications which demand low OEM unit cost, robust design, setpoint accuracy, and high reliability.

MPL 9300 features a unique integral snap switch, with positive snap action and self-wiping silver contacts for ultra-reliable switching.
