flottörbrytare

Flottörbrytare, also known as a float switch, is a mechanical device used to detect the level of liquid in a tank or container. It operates by a buoyant component, the float, which rises or falls with the liquid level. Attached to the float is a lever arm or stem that, at a specific liquid level, activates an electrical switch. This switch can then be used to control pumps, alarms, or other electrical systems.

There are several types of flottörbrytare. One common design uses a simple float and a single-pole, double-throw (SPDT) switch. As the liquid level changes, the float moves, tilting the lever and actuating the switch. Another type uses a magnetic reed switch. In this configuration, the float contains a magnet, and as it rises or falls, it passes a reed switch, causing it to open or close an electrical circuit. Some flottörbrytare are designed for multiple switching points, allowing for more complex control strategies.

Flottörbrytare find widespread application in various industries. They are commonly used in sump pumps to automatically activate when water levels rise, in water treatment plants to control pumps for filling or emptying tanks, and in industrial machinery to monitor fluid levels in hydraulic systems. They are also found in domestic appliances like washing machines and dishwashers to manage water intake and drainage. The simplicity and reliability of flottörbrytare make them a cost-effective solution for liquid level detection and control.
