Description

The PSW8 series has been discontinued. Please see the PSW-500 as a possible alternative or contact our Engineering department.

OMEGA’s new modular series general purpose compact pressure switches, offer a proven design for stationary or mobile hydraulic applications. Applications include factory automation, balers, compactors, overload controls, machine tools, hydraulic power packs, railway, and marine applications. PSW8 series is available in a wide range of configurations. Low pressure ranges feature a diaphragm pressure switch design. Higher pressure ranges feature a compact piston design. A SPDT micro switch will change state on increasing pressure at your set-point, and will reset when your pressure decreases back below the set-point by the amount of the deadband.
