PCB Mount Pressure Switches
Printed Circuit Board (PCB) mount pressure switches are compact SPST switches designed for applications where moderate pressure accuracy is acceptable. Pressure ranges span from 6 inches of water to 65 PSIG. Actuation points are specified by the customer and set at the Presair factory, with select models offering field adjustment capability.
custom options
Wide variety of options available to meet original equipment manufacturers product requirements.
high quality
Highly stable with good repeat accuracy. All switches are 100% tested at high & low settings & at proof pressure.
safe & economical
Remote operation with complete electrical isolation. UL Recognized. Costs less than conventional controls
made in u.s.a.
Presair switches are designed & manufactured in Eau Claire, Wisconsin U.S.A.
Printed Circuit Board (PCB) mount pressure switches are single-function controls with internal electrical contacts, designed for direct integration into printed circuit boards. These compact switches provide momentary switching logic and enable pneumatic actuation within electronic control circuits.
Built for space-constrained applications, these switches offer various connection styles and can also be retrofitted by attaching wire leads. Despite their small size, they support a broad pressure sensing range—from 6 inches of water to 65 PSIG—making them suitable for a wide range of low to moderate pressure systems.
