Magnetic Tank Float Level Switch
MTC is a supplier in the Philippines of Magnetic Level Switches. If you are looking to buy a highly reliable switch in PHP/Peso which is cost-effective, then look no further.
The Magnetic Float Switch device is used to detect and control the level of liquids in tanks, vessels, and pipelines. Whether used for pump control, overfill protection, or level alarms, it plays a vital role in many industrial applications throughout the Philippines.
What Is a Magnetic Float Level Switch?
A magnetic level float switch is a type of liquid level sensor that uses a magnet embedded in a float and a reed switch inside a sealed stem to detect the presence or absence of liquid. As the liquid level rises or falls, the float moves accordingly, triggering the reed switch when it reaches a specific point.
This switching action can be used to:
Activate alarms
Control pumps
Open/close valves
Send signals to control panels
How does the Magnetic Float Level Switch Work?
Float – Moves up or down with the liquid level. It is designed to slide along a non-magnetic stem or tube. The float is a hollow component made from buoyant material such as plastic or stainless steel. It contains a small permanent magnet inside.
Reed Switch – A pair of magnetic, flexible metal contacts sealed within a glass tube. When the magnet in the float comes close to the reed switch, the magnetic field causes the reeds to either close (make contact) or open (break contact). This change in state acts as an electrical signal to control or monitor a system.
Switch Activation – As the liquid level rises or falls, the magnet inside the float moves with the liquid. Once the float reaches the switch position, the magnetic field activates the reed switch. The switch state changes from open to closed (or vice versa), sending a signal to connected devices.
Types of Switching Action
Normally Open (NO): The circuit is open until the float rises to the switching point.
Normally Closed (NC): The circuit is closed until the float drops below the switching point.
Some magnetic float switches offer multi-point sensing for high/low level monitoring.
Common Applications
- Water treatment plants
- Oil and chemical tanks
- HVAC systems
- Food and beverage production

Things to Consider When Choosing a Magnetic Float Switch for Level
- Liquid type and compatibility (corrosive, viscous, etc.)
- Mounting style (top-mount, side-mount, vertical)
- Operating temperature and pressure
- Switch rating (voltage/current requirements)
- Material construction (plastic, stainless steel, etc.)
