SH-3 series NPT mount SPDT switch 1 1/2”NPT or 2”NPT thread external mount SS 316L float material SS 304 other wetted parts material Available in direct switching version for use at up to 100ºC or low power switching at up to 200ºC Aluminium enclosure with screw on lid and cable gland Technical Specification The SH-3 series are NPT mount horizontal float operated level switches. This design uses a pivoted float arm with a magnet on the inboard end. This magnet when moved by the rising float arm interacts with another magnet in the switch enclosure to give a snap action operation. Two switching options are available using either microswitches or reed switches, for different switching power and operating temperature ranges. Available with either 1 1/2”NPT or 2” NPT thread mounting.
