What is a double-ball side mount stainless steel float level switch used for?

This float switch is mainly used for liquid level detection and automatic start-stop control in tanks, reservoirs, chemical containers, oil tanks, sewage treatment systems, and industrial automation equipment. It is especially suitable for: Pump start and stop control Automatic drainage systems Water supply systems Wastewater treatment tanks Industrial tanks requiring larger level differential Compared with single-ball models, double-ball float switches provide a wider control range, more stable switching, and help reduce frequent pump starting.

What material is the float switch made of?

The standard model uses SU304 stainless steel, including both the float balls and the float body, which provides: Excellent corrosion resistance High temperature resistance Strong mechanical strength Long service life Suitable for water and many industrial liquids For stronger corrosion resistance, some applications may also require 316 stainless steel customization, especially for chemical liquids or marine environments.

Is this switch normally open (NO) or normally closed (NC)?

It supports both. The float balls can be manually reversed by 180° rotation, allowing users to switch between: Normally Open (NO) Normally Closed (NC) Factory default is usually the lower-open setting, but users can adjust according to actual control requirements. This provides more flexibility for different installation and automation systems.

Can the float switch directly control pumps or solenoid valves?

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: For alarms or solenoid valves → use a small relay (such as HH52P / HH54P) For water pumps → use relay + AC contactor Direct connection may damage the reed contacts and shorten service life.

What is the switching capacity?

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

What is the control stroke of the double-ball float switch?

The control stroke of the double-ball float switch is usually much larger than single-ball models, commonly ranging from 30mm to 50mm or more, depending on the rod structure and float spacing. This larger liquid level differential is ideal for: Preventing frequent pump start/stop Protecting motors and relays Improving equipment lifespan Stable automatic liquid level control This is the biggest advantage of double-ball float switches.

Can the rod length, float spacing, and thread size be customized?

Yes. ELECALL supports: Rod length customization Float spacing customization Thread size customization Float quantity customization Special mounting requirements OEM / ODM production This is especially useful for distributors, equipment manufacturers, and project buyers with specific installation requirements.

Is it suitable for dirty water or liquids with impurities?

Compared with single-ball models, double-ball float switches are generally more suitable for: Slightly dirty water Industrial wastewater Cooling water systems Light oil liquids Low-viscosity industrial media Because of the larger operating differential and more stable switching structure, they perform better in practical industrial environments. However, for heavy sludge or liquids with large debris, cable float switches may still be a better choice.

Can the float position be adjusted freely?

No. The float ball positions are fixed by retaining clips, and the internal reed switch positions cannot be moved freely. Simply moving the clips usually does not effectively change the switching point. If special switching positions or liquid level differences are required, buyers should request customized dimensions before production.

What should buyers confirm before purchasing?

Before placing an order, buyers should confirm: Liquid type (water / oil / chemical / wastewater) Working temperature Working pressure Installation direction Mounting thread size Rod length Required cable length Normally Open or Normally Closed logic Voltage and current requirements Required liquid level differential distance Float spacing requirements Quantity and customization needs Clear specifications help avoid installation problems and improve system compatibility.

Does ELECALL support bulk orders and distributor cooperation?

Yes. ELECALL is a professional industrial measurement and control manufacturer established in 2008, providing: CE / ROHS certified products OEM / ODM customization Factory-direct pricing Low MOQ Export support Distributor cooperation This makes ELECALL suitable for wholesalers, importers, industrial system integrators, and long-term project buyers.

Why choose a double-ball float switch instead of a single-ball model?

Choose a double-ball float switch if: A larger liquid level difference is required Pump protection is important Frequent motor starting must be avoided Stable start-stop automation is needed The tank has enough installation space Choose a single-ball float switch if: Installation space is limited Only point-level detection is needed High sensitivity is required Compact tank design is preferred The right choice depends on the actual application and control requirements.
