Purn Sanket Electrols manufactures HK magnetic float level switches and industrial float switch sensors for tanks, pumps, utilities, and process applications across India—built for stable switching, long service life, and easy panel integration. Our instruments are designed for reliable liquid level detection in water tanks, hydraulic systems, and chemical processing units across India.
Whether you need a simple water float switch for a pump or a complex multi-point magnetic level switch for PLC automation, our sensors ensure stable switching and long service life.
Best for:
A magnetic float level switch works on the buoyancy principle—when the liquid level changes, the float moves and its internal magnet actuates a sealed reed switch inside the stem to open/close the circuit.
This simple, non-contact mechanism makes the float level switch highly reliable compared to complex electronic sensors.
We manufacture a wide range of magnetic float level switches to suit different tank geometries.
Ideal for horizontal installation on tank walls. These float switch sensors are perfect for high/low-level alarms.
Designed for vertical installation from the top of the tank. These are often used as the primary water level float switch for deep tanks.
Need to control multiple pumps or alarms? Our multi-point magnetic float level switches allow for up to 4 switching points on a single stem.

A magnetic float level switch is a sensor that uses a buoyant magnetic float to actuate a reed switch, providing a signal when liquid reaches a specific level. It is widely used as a reliable float switch sensor for tanks.
Yes. However, since the float switch sensor provides a potential-free contact (low current), you should use it to trigger a relay or contactor which then switches the heavy pump motor.
Yes, Purn Sanket Electrols manufactures custom magnetic float level switches with specific stem lengths and multiple switching points tailored to your tank depth.
Side-mount is compact for lateral entry; top-mount is preferred for vertical stems and multi-point level switching (choose based on tank access and switching points).
Yes—contact configurations vary by model and requirement (share your control logic and load type).
For high loads, use a relay/contactor interface; share motor/load details so we can recommend safe switching.
SS304/SS316 and engineered plastics (PP/nylon) are available depending on media compatibility.
Use proper mounting location, damping/guarding if needed, and confirm SG/float selection for your media.
Multi-point options are available (share switching point distances and mounting details)
