Tecmark Series V4000 Vacuum Switches convert a negative pressure signal to an electrical output. In response to a change in negative pressure, movement of an elastomeric diaphragm opens or closes an electrical circuit based on a predetermined pressure set point. The Series V4000 features cost effective, snap-acting electrical switches and field adjustable set points. Vacuum ranges from -2.5" (-600 Pa) Water Column (W.C.) to -10.75 PSI (-75 kPa) are available. Consult factory for vacuum levels outside listed ranges. Series V4000 switches assure control stability through wide and variable temperature and humidity conditions and assure uninterrupted service under extreme shock and vibration. As with all Tecmark® products, series V4000 switches provide superior performance and 100,000 cycle life under full mechanical, electrical and thermal loads.
