Mainline Pressure Switch

A Mainline Pressure Switch is installed on the mainline of a medical gas supply system and provides high and low setpoints that can notify staff if the medical gas pressure were to increase or decrease unexpectedly. These switches provide a single pole double throw snap-action microswitch that sends a single to the Medical Gas Master Alarm Panels. These switches are provided with or without a pressure gauge and include a DISS demand check for code compliance.
