The PSW23V-200W Omega pcb vacuum switches are manufactured by Presair cross referencing to our printed circuit board mounted vacuum switches. The PSW23V-200W pcb vacuum switch is factory set at 200 inches of water and is UL rated at 1 amp resistive 250 Vac. PSW23V-200W is single pole, single throw (SPST) and has a 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 set point is factory set.
PCB 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.
