The Saier SEN-SSI45 Float Level Switch operates on a simple mechanical principle, where a buoyant float actuates an internal reed or micro-switch as the liquid level rises or falls. This action opens or closes the electrical contact, providing a direct switch signal for monitoring or control purposes.
Designed for long-term durability, the switch features robust construction suitable for various liquids. Its high insulation and low contact resistance ensure reliable performance and signal integrity when integrated into industrial control panels, home water tank systems, or IoT-based monitoring setups.
