Presair
Printed Circuit Board Mount Switches
Miniature single-pole and double-pole printed circuit board (PCB) mount switches are used for pressure, vacuum, or differential pressure sensing in applications where moderate accuracy is acceptable. These switches are also suitable for use as air switches when paired with pneumatic actuators.
PCB mount switches are single-function controls with internal electrical contacts, designed to install directly onto a printed circuit board. Their compact design and momentary switching logic enable pneumatic actuation within electronic control circuits.
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.
PCB MOUNT PRESSURE SWITCHES
Printed circuit board (PCB) mount pressure switches are miniature single-pole and double-pole devices used in applications requiring moderate pressure accuracy. Pressure sensing ranges from 6 inches of water gauge (IN.W.G.) to 65 PSIG. Each unit is factory set to a customer-specified actuation point, with the set pressure clearly marked on the switch housing. Select models include field adjustment capability for flexible integration.
PCB MOUNT VACUUM SWITCHES
Miniature single-pole and double-pole switches designed for vacuum sensing in applications where moderate accuracy is sufficient. Vacuum ranges span from 6 to 200 inches of water gauge (IN.W.G.). The actuation point is specified by the customer and factory set by Presair, with the set point clearly marked on the switch housing. Select models include field adjustment capability.
PCB MOUNT AIR SWITCHES
The Printed Circuit Board (PCB) Mount Air Switch is a compact single-pole or double-pole switch designed for integration with Presair actuators. These switches are suitable for a wide range of applications due to their small footprint and multiple connection options.
While intended for direct mounting to a printed circuit board, these switches can also be retrofitted into non-PCB systems by connecting wire leads, making them a flexible solution for both new and existing designs.
