Features

miniature floating switches feature a floating probe to detect high / low levels in a container.
These polypropylene switches are ideal for low-temperature food equipment, agriculture applications, or contact with many industrial fluids.
They can be installed in a vertical or horizontal position for the user's convenience and can withstand a maximum temperature of 392 degrees F.
They come with field-adjustable stem lengths that can be extended with pipe to meet custom tank / container depth.
Multi-level float switches control multiple switch points, pumps & valves, warning alarms and many more.
These versatile switches are available in polypropylene / Buna N / 316 SS float material to cater to varied applications.

Madison Single-Point Liquid Level Switches

These switches are made of polypropylene / 304 stainless steel to ensure long-lasting performance and resistance to corrosion.
They have SPST (single pole, single throw) configuration for a simple and reliable circuit configuration.
They can handle pressures up to 900 psi and temperatures up to 300 degrees F.

Square D Liquid 2-Level Switches

They can operate effectively within a temperature range of -22 to 220 degrees F.
These switches operate on a 'Close On Rise' function, meaning that they close the electrical circuit when the liquid rises to the desired level.
They include a stainless steel float, ensuring durability and resistance to corrosion, even in harsh liquid environments.
These level switches have the float positioned below the liquid level, enabling them to rise and trigger when the liquid reaches the desired level.

Parker Level Switches

They can withstand temperatures ranging from 0 to 60 degrees C.
These switches are extremely sensitive and have built-in springs that can be adjusted to four different levels.
