SW-11 Magnetic Switch

SW-11 Magnetic Switch is externally mounted on Magnetic Level Indicator of Flap-11 series products to achieve automatic control and remote control.

● Use the power reed of international famous brands, which with capacity of heavy current and long service life.

● The guide tube is made of 304 material, with strong corrosion resistance.

● Has got double certifications of Explosion Proof and Intrinsically Safety.

● The ingress protection grade reaches to IP66/67.


  • SW-11 Magnetic Switch uses the power reed of international famous brands as its core components and is designed with aluminum housing. It is certificated with Flame proof Enclosures and Intrinsic Safety (Explosion-proof grade Exd IIC T6,Intrinsically Safe rating Exia IIC T6), which is the highest level of similar products in peer industry. As the measured fluid level rises and drops, the magnetic float rises and drops as well, and when the permanent magnetic steel within the magnetic float moves close to the switch, it stimulates the attached switches, triggering reed switch’s status to change, and providing a signal back to the control system to realize the liquid level control.


    The output of the switches can be configured with SPST or SPDT, and can be set as anti-overflow or anti-dry protection.
