Product Description

A differential pressure switch is a device which utilizes a differential air pressure to actuate an electric switch at a pre-set actuation point. This may be the difference between two positive or two negative pressures, one of each, or a positive and atmospheric or a negative and atmospheric pressure. The electric switch may be used to start or stop motors or fans, open or close dampers or louvers, light a warning signal, sound alarms, etc.
