The Dwyer Instruments 1638-2 Diaphragm Vertical Pressure Switch is a diaphragm-type sensor that detects pressure and actuates electrical contacts in a vertical configuration. It uses a Type 1 enclosure and lists a 10 PSI activation setting with a 480 VAC rating. This compact switch supports diaphragm-based pressure sensing for industrial control tasks requiring precise, switch-level response at moderate pressures.
