eries SA1100 Pressure Switches actuate one or two single pole, double throw

(

SPDT) snap switches in response to increasing or decreasing pressure of

ompatible gases or liquids. Three field adjustable operating ranges are available

allowing setpoints up to 500 psig (35 kg/cm

). All models are weather-proof and

suitable for hazardous locations as detailed in the chart at lower right. Read and

understand these instructions completely before proceeding with installation or

operation.
