What is the installation type of this float switch?

This is a side-mounted float switch, installed on the side wall of tanks or containers, making it ideal for compact spaces and small tanks.

Why is it called a “duckbill type” float switch?

The float has a flattened, elongated shape similar to a duckbill, allowing it to operate in limited spaces and respond quickly to liquid level changes.

What should I confirm before purchasing?

You should confirm: Mounting hole size and thread type Tank wall thickness Required switching position (high level / low level) Voltage and current requirements Cable length or terminal type

Is it normally open or normally closed?

It can be configured as NO or NC by changing the float orientation during installation.

What liquids can it be used in?

It is suitable for water and general liquids compatible with PP material, including some weakly corrosive media.

Can it be used in high-temperature environments?

PP plastic float switches are generally suitable for low to medium temperature environments (typically below ~85°C). For higher temperatures, stainless steel models are recommended.

What are the advantages of this design?

Compact and lightweight Ideal for small tanks or tight spaces Simple structure with reliable operation Easy installation from the side

Can it directly control pumps or valves?

No. The internal reed switch has limited current capacity. A relay or contactor is required for controlling high-power devices.

What problems may occur if the wrong model is selected?

Possible issues include: Float stuck due to improper installation space Incorrect switching point Material incompatibility with liquid Reduced service life

What applications is this product best suited for?

It is commonly used in: Small water tanks Coffee machines / water dispensers Air conditioning drainage tanks Compact industrial containers
