Truly "Contactless": Uses capacitive field changes—no internal moving parts or exposed electrodes—eliminating wear, oxidation, and corrosion. Exceptional Lifespan: Switching is electronic, enabling a theoretical lifespan of tens of millions of cycles, exceeding appliance life for "install and forget" reliability. Superior Noise Immunity: Advanced circuitry counters electrical noise from pumps and valves, ensuring accurate switching and preventing false triggers.
