Presair
Printed Circuit Board Mount Switches
These miniature single pole and double pole printed circuit board (PCB) mount switches are used as pressure, vacuum, or differential pressure switches where moderate accuracy is sufficient. The printed circuit board mount switches are also suitable for use as air switches in conjunction with air actuators.
PCB mount switches are single function controls with internal electrical contacts designed to mount directly to a printed circuit board. These basic component switches feature momentary switching logic in a compact design to add pneumatic actuation to any electronic control circuit.
custom options
Variety of options available to meet the needs of original equipment manufacturers.
high quality
Highly stable with good repeat accuracy. All switches are 100% tested at high and low settings and 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 mount pressure switches are miniature single pole and double pole switches used as pressure switches where moderate accuracy is sufficient. Pressure ranges: 6 IN.W.G. to 65 PSIG. Pressure setting marked on switch in inches water gauge. Actuation point is customer specified and set at the Presair factory. Some models allow field adjustment.
Rating: 1 AMP resistive @ 250 VAC. Ratings are dependent on actuation pressure and must be de-rated at lower pressures. UL recognized for 100,000 operations.
Material: Rynite/acetal body, silicon diaphragm, gold pins and contacts, stainless steel springs and screws.
