Pressure Switches

Pressure Switches provide electrical switching when pressure reaches an adjusted or fixed setpoint. Products in this category span Omega Engineering and Dwyer Instruments industrial switches, digital miniature switches with displays, vibration-resistant switches for hazardous locations, OEM mechanical switches, hermetic and NEMA 4X switches, heavy-duty NEMA 7 and NEMA 9 switches, steam-cleaner switches, and compact high-sensitivity models.

Applications include:

Pump, compressor, and hydraulic pressure control
Industrial high or low pressure alarms
OEM equipment and compact machine protection
Hazardous, harsh, vibrating, or high-current applications when supported by the selected switch

Choose by setpoint range, deadband, contact rating, pressure media, diaphragm or seal material, enclosure, approvals, and reset behavior.
