Water Level Float Switch 3m Cable Liquid Level Controller for Water Tank and Sump Pump Automatic Level Control

Product overview This liquid level switch senses when liquid reaches preset upper or lower switching points and activates the controller contact to send a signal. It is designed to monitor and regulate water level in barrels, sinks, wells and similar tanks. The non toxic construction makes it suitable for residential and industrial applications where contact with water is required. Key benefits Automatic level control to reduce manual monitoring and maintenance effort. Protects pumps and equipment by enabling automatic start and stop at set levels. Dual contact output (normally open and normally closed) for flexible integration with existing control systems. Durable electrical performance with an electrical endurance of 50,000 cycles for long service life. Clear compatibility with common supply and control voltages for straightforward installation. Features and specifications Function: Sends a signal when liquid reaches upper or lower switching values to control pumps or alarms. Contacts: Normally open and normally closed outputs for flexible wiring options. Recommended supply: DC 24 V for control circuits. Rated current and voltage: AC 10(8A) 250 V and 10(4A) 380 V. Control range: 0.2 m. Operating temperature: 0 to 60 degrees C. Construction: Non toxic type suitable for household and factory water applications. Electrical endurance: 50,000 cycles. Compatibility and performance Integrates with controllers and pump starters that accept NO or NC contact inputs. Recommended for systems using a 24 V DC control supply; contact ratings also support direct AC switching within specified limits. Control range of 0.2 m provides reliable switching for common tank and well depths within that span. Practical applications Rainwater harvest barrel: Automatically control a pump to transfer collected water when the barrel reaches set or low levels. Sink or sump drain: Activate an alarm or pump when a sink or sump reaches the upper or lower switching points to prevent overflow or dry running. Small well or storage tank: Maintain water level by triggering a pump or valve at preset levels using the NO or NC contact outputs. Installation notes Use the normally open or normally closed contact as required by your control logic. Follow recommended DC 24 V supply for control response; when switching AC loads, ensure connection remains within the rated current and voltage limits. Verify the 0.2 m control range meets your application spacing between sensors or probes. This liquid level switch provides straightforward, reliable level sensing and control for residential and industrial water applications without introducing toxic materials.
