The PSW-300 series are SPDT switches with fixed or adjustable deadbands that are UL listed and CSA certified along with a NEMA-4X enclosure for harsh environments.

Ideal for use in harsh and corrosive environments, the PSW-300 Series pressure switches feature stainless steel or Buna-N diaphragm-sealed pistons or diaphragm actuators that provide repeatability of ±1% of range. Standard design allows easy access to switches. For versatility, single setpoint with adjustable deadband or dual, independently adjustable setpoints with fixed deadband may be chosen.
