How It Works – Reed Switch
The magnetic float rises or falls with the liquid level, its magnetic field activates the reed switch at a defined point. The sealed contacts close or open instantly, providing a precise, reliable signal for level indication or alarm. With no process contact and no moving parts to wear, the design ensures simple, maintenance-free operation and long service life.
