Stainless Steel Float Switch Water Level Sensor Water Level Controller Sensor Switch M10 for Smart Toilet Solar Tank Pool Pump Liquid Control Length 200mm Silver

Industrial-Grade Smart Water Level Control Solution
This float switch employs magnetic induction principle, where the float triggers the internal reed switch as water level rises/falls: when water reaches the set height, the built-in magnet approaches the reed switch to close the circuit; as water level drops, the magnet retracts to open the circuit. With pure mechanical design, it ensures stable operation in electromagnetic interference environments, ideal for industrial liquid level automatic control.
Standardized Installation & Operation Guide
Installation Specifications：Vertical or laterally mounting via M10 standard thread, select top (high water level) or bottom (low water level) installation based on monitoring needs, with a sealing washer to ensure watertightness.
Mode Switching：Flip the float 180° to switch between Normally Open (NO)/Normally Closed (NC) modes without circuit adjustments, adapting to different equipment control logics.
Electrical Connection Notice：Rated at 0.5A/110VDC, do NOT connect directly to high-power loads (pumps, solenoid valves). Use an intermediate relay to prevent product failure from overload.
Diversified Applications
Industrial Sector：Suitable for water level monitoring in chemical tanks, water treatment systems, cooling towers, etc., linking with pumps to prevent equipment failure from water shortage/overflow, enhancing process stability.
Civil & Commercial Equipment：Can be integrated into swimming pool auto-refill systems, aquarium smart water change devices, commercial coffee machine water level control, etc., realizing automated liquid level management and reducing manual inspection costs.
Special Environments：Performs excellently in corrosive environments like chlorinated pool water or weak acidic chemicals, resisting rust/aging for long-term reliable operation.
Caution: The float switch features a 0.5A switching current and 110VDC max breakdown voltage that CANNOT directly control solenoid valves, water pumps, (contact power 10W). Always use a small relay for transition —otherwise may cause overload or failure
Size:The water level sensor switch total length: 200mm(7.87in), wire length: 300mm(11.8in), float diameter is 26mm(1.02 in),thread: M10,package contains 1 pcs stainless steel float switch
Material: Entire body & ball made of corrosion-resistant 304 stainless steel with exceptional resistance to rust, weak acids and alkalis.Perfect for saltwater pools, industrial sumps, and harsh environments
Convenient and flexible:Flip the float 180° to switch between Normally Open (NO) and Normally Closed (NC) modes,mount at tank top (detect rising) or bottom (detect falling)
Applications: This float switch is designed specifically for solenoid valves, liquid level indicators, alarms, etc. It is widely used in pools, garden ponds, aquariums, water tanks, HVAC drainage, industrial sewage pumps, and solar heating systems
