Single point float level switch. Normally open (N/O) / normally closed (N/C) with 1/2 in NPT thread.
Provides a simple, inexpensive control of the liquid level within a tank. Suitable for many solid-state control systems and monitors or alarms. Simple relay interfaces can be used for higher current applications. Hermetically sealed reed switches are actuated by magnets permanently bonded inside the float and can be easily adapted to open or close a circuit on rising or falling levels.
