The PSW490 has been discontinued. Please see the PSW-100 SERIES as possible substitutes or contact our Pressure department.
OMEGA’s PSW490 Series of switches are designed to satisfy most
industrial switch requirements. The actuators have been proven in more
than 20 years of service worldwide. A Buna-N seal and SPDT switch is
standard. Optional FKM or stainless steel seals extend media
compatibility to most fluids, and either the hermetically sealed or dual
SPDT switches will meet most switching applications.
