This float switch is mainly used for liquid level detection and automatic control in tanks, reservoirs, industrial containers, water treatment systems, and pump control systems. It can be used for: Pump control Overflow protection Dry-run protection Alarm systems Automatic liquid level monitoring The 1-inch threaded design provides stronger installation stability and is suitable for larger tanks or industrial equipment.

The float ball and float body are made of SU304 stainless steel, offering: Excellent corrosion resistance High mechanical strength High temperature resistance Long service life For more demanding environments, 316 stainless steel customization is also available.

It supports both Normally Open (NO) and Normally Closed (NC), depending on the float orientation. The switching logic can be changed by reversing the float by 180°. Lower-Open Type (Default) ① When the liquid level rises, the float moves away from the reed switch position, and the switch turns OFF. ② When the liquid level falls, the float returns to the reed switch position, and the switch turns ON. Upper-Open Type ① When the liquid level rises, the float returns to the reed switch position, and the switch turns ON. ② When the liquid level falls, the float moves away from the reed switch position, and the switch turns OFF. Note The factory default is usually the lower-open type, but users can adjust it according to control requirements.

No. Because the internal reed switch carries only a small current, it should not directly control high-power loads such as: Water pumps Solenoid valves AC contactors Large alarms Recommended solution: Solenoid valves or alarms → use a small relay Water pumps → use relay + AC contactor Direct connection may burn the reed contacts.

Typical specifications include: Max Contact Rating: 10VA / 50VA Max Switching Voltage: 100V AC/DC or 220V AC/DC Max Switching Current: 0.5A / 1.5A Max Breakdown Voltage: 110V AC/DC or 300V AC/DC Temperature Rating: -30°C to +120°C Actual specifications may vary depending on the selected model.

Compared with smaller threaded models, the 1-inch thread design provides: Stronger installation stability Better sealing performance Higher mechanical strength Better suitability for large tanks Easier compatibility with industrial pipelines This makes it suitable for industrial liquid level control applications.

Yes. ELECALL supports: Rod length customization Thread size customization Float quantity customization Cable length customization OEM / ODM production Non-standard customization is supported for different installation requirements.

Suitable for: Water Light oil Cooling liquid Industrial liquids Chemical media compatible with stainless steel Not recommended for: Heavy sludge Liquids with large floating debris Because floating objects may affect switching stability.

Buyers should confirm: Liquid type Working temperature Working pressure Installation direction Thread size Rod length Cable length NO or NC logic Quantity Customization requirements Clear specifications help avoid installation problems later.

Compared with single-ball models, double-ball float switches provide: Larger liquid level differential More stable switching Better pump protection Reduced frequent start/stop This is especially useful for automatic pump control systems.

Choose double-ball if: A larger liquid level difference is required Pump start/stop control is needed Frequent motor starting should be avoided The tank has enough installation space Double-ball models help improve system stability and extend pump lifespan.

Yes. The float spacing can be customized according to the required liquid level differential and installation structure. This helps improve control stability for different industrial systems.
