Description :

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.
