Tecmark Corp.'s 3000 series pressure switches convert a pressure signal to an electrical output. In response to a change in pressure, movement of an elastomeric diaphragm opens or closes an electrical circuit based on a predetermined pressure set point. The Series 3000 features cost effective, snap-acting electrical switches and field adjustable set points with a visual scale for easy set point selection. Pressure ranges as low as 2" Water Column (W.C.)* up to 100 PSI are available. Typical applications include gas heaters, pumps, small air compressors and residential boilers.
