Products are screw adjustable but are factory fitted with specific pressure rated springs which are not interchangeable. As the contact pressure is dependent on the air pressure, the switch rating will be reduced when used at the minimum operating pressures. The connection terminals on this version exit vertically downwards from the lowest face in relation to the image shown above.
