产品描述

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.
