The PSW23-1P Omega pcb pressure switches are manufactured by Presair cross referencing to our printed circuit board mounted pressure switches. The PSW23-1P pcb pressure switch is factory set at 1 Psi and is UL rated at 1 amp resistive 250 Vac. PSW23-1P is single pole, single throw (SPST) and has 1/8 MNPT fitting with center spout for 1/8″ ID tubing.
These miniature single-pole switches are used in pressure and vacuum applications in which moderate accuracy is sufficient. The fixed setpoint is factory set.
