MADISON Plastic Single-Point Liquid Level Switches
Madison plastic single-point liquid level switches regulate and monitor the oil or water level in a container. These units float on the top of the liquid surface and notify users when the liquid surface goes up or down. They are used in pumps, valves or alarms.

Working Mechanism
- Install the liquid level switch in the desired tank or container, ensuring proper positioning and mounting to allow free movement of the float with the liquid level changes.
- Connect the electrical contacts of the liquid level switch to the appropriate circuit or control system.
- Set the desired level thresholds for the switch by adjusting the positioning of the float.
- When the process liquid displaces the float, the float lever pivots within the body.
- The magnet on the float lever's opposite end controls a second magnet on the switch actuating lever in the switch housing.
Features
- Madison plastic single-point liquid level switches feature a selectable switch function, allowing for versatile application adaptability.
- They come with a vertical / horizontal open tank mounting design, optimising liquid level monitoring in various industrial contexts.
- These liquid level switches are equipped with a Buna N float material, enhancing durability and reliability in liquid environments.
- They feature an SPST / SPDT contact form, providing a reliable single-pole, single-throw electrical connection.
- These liquid level switches have an operating temperature of up to 149 / 221 / 266 / 392 / 482 degrees F, ensuring performance in diverse temperature conditions.
Frequently Asked Questions
What is the purpose of the float level sensor?
These continuous-level sensors feature a magnetic float that can rise and fall as liquid levels change. The float movement creates a magnetic field that actuates a hermetically sealed reed switch (located in the stem of the liquid sensor), thereby triggering the switch to open / close.
What are side mount level switches used for?
The side mount level switches can rotate 180 degrees and monitor liquid rise or fall in a tank. These encapsulated, magnetically coupled dry reed units can deliver more than 5 million switching cycles to control motor starters, solenoids, contractors and relays.
