The PSW24V-100W Omega pcb vacuum switches are manufactured by Presair cross referencing to our printed circuit board mounted vacuum switches. The PSW24V-100W pcb vacuum switch is factory set at 100 inches of water and is UL rated at 1 amp resistive 250 Vac. PSW24V-100W is single pole, single throw (SPST) and is a threaded mount 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.
