The weight of standard models is 180 g. These pressure switches can be used to sense the presence or absence of pressure and to switch on or off electrical circuits when the predetermined pressure is reached. They can be supplied in 1 SPDT and 2 SPDT microswitch versions. The switches can be used for a variety of working media by selecting the appropriate wetted parts. The electrical switching element is an SPDT snap-action microswitch for reliable changeover. The microswitch is rated at 5 A, 250 V AC, 0.2 A, 250 V DC. Applications are in lubrication systems, to prevent excess pressure build-up in hydraulic/pneumatic cylinders, spot welding machines, for pneumatic clamping jigs and fixtures with predetermined pressure, textile machinery, safety systems and point systems. Pressure switches are also offered in various ranges from 15 mm WG to 400 bar.
