This stainless steel float switch senses liquid levels. It can automate pumps or trigger alarms. As water or other liquids go up and down, the float moves on the stem. This activates a switch inside. It's a straightforward way to check tank levels. Features and Benefits
- 304 or 316L stainless steel body - It resists rust and corrosion. This makes it good for water, fuel, oils, and some chemicals.
- Sealed internal reed switch - The electrical contacts are kept away from the liquid. This means safe and steady operation.
- Reversible float for NO/NC action - You can set the switch to turn on for a high or low level. Just flip the float over.
- Multiple lengths and ball options - Choose from 45mm to 400mm sizes. You can get a single or double ball float. This matches your tank's depth. Applications
- Controlling a sump pump. It automatically removes water when it reaches a certain level.
- Managing the fill cycle in a water tank. This works for a well or rainwater system.
- Checking high and low levels in industrial tanks. This stops overflows or pumps from running dry.
What It Is
A float switch is a device used to sense the level of liquid within a tank. This particular model is a steel float switch, featuring a dual ball design for accurate tank level sensing. It operates as a physical switch, typically controlling a pump or alarm when the liquid reaches a predetermined level. The internal switch mechanism relies on the movement of the float balls.
Key Uses & Applications
This steel float switch is designed for a range of liquid level sensing applications. It functions as a water level sensor, ideal for monitoring levels in tanks, sumps, or reservoirs. Its robust stainless steel construction makes it suitable for various liquids. It can also be employed as a pool flow sensor, detecting changes in water movement within a pool system.
How to Choose
When selecting a float switch, consider the required length range, which for this product is 45-400 mm. The dual ball switch type offers precise level detection. Evaluate the material; stainless steel provides durability for many applications. For automated systems, a float switch acts as a reliable sensor to trigger pumps or alarms via a reed switch or relay.

Q: What sizes do these come in, and what temperatures can they handle? A: We carry a wide selection of stem lengths, from 45mm up to 400mm, to fit tanks of various depths. They are rated to work in liquids ranging from a cold -30°C all the way up to a hot +125°C (-22°F to 257°F).. Q: What material is this float switch made of? Is it safe for drinking water? A: The stem, retaining clips, and float balls are all constructed from 304 stainless steel. This material resists rust and corrosion, and it's considered food-safe, making it a good choice for potable water tanks or food-grade liquid applications.. Q: Can I use this one switch to control both the high and low levels in a tank? A: Yes, that's exactly what this double-ball switch is for. You can configure it to trigger a pump or an alarm for both a high-level and a low-level event, all with a single device.. Q: What is the warranty if the switch stops working after a few months? A: These switches are built for long-term service. If yours fails within one year of purchase under normal operating conditions, please reach out to us, and we'll help you with a replacement.. Q: Why would I choose a double-ball float switch over two separate single ones? A: Using a double-ball switch simplifies your setup because you only have one component to install and wire. It's generally more economical and saves space inside your tank compared to mounting two individual switches..
