OMEGA’S PSW12 offers reliability, repeatability, and durability in a compact design. This switch is rack mountable and has an accessible adjustment when installed. Snap­action Belleville spring design contributes to a long, stable life and to vibration resistance. An optional mounting bracket provides easy retrofit, and an optional cover lock adds security. Ranges are from 8 to 6000 psi (0.6 to 414 bar).
