Low pressure, slow action contact differential pressure switches for printed circuit boards with 6.35mm pitch
Uses: Low voltage, high sensivity
Main applications: Electronic printed circuits. Detection of low positive, negative or differential pressure. Measurement of liquid levels, air flow, filters efficiency. Very small differential, about 2 millibars
