Úszókapcsolókat

Úszókapcsolókat, also known as float switches, are electrical switches activated by the level of a liquid. They typically consist of a buoyant element, such as a float, connected to a switch mechanism. As the liquid level rises or falls, it moves the float, which in turn actuates the switch. This actuation can be used to start or stop pumps, activate alarms, or control other liquid-handling equipment.

There are several types of úszókapcsolókat. One common design uses a mercury switch enclosed in a sealed housing. As the float moves, it tilts the housing, causing the mercury to flow and complete or break an electrical circuit. Another type employs a mechanical switch that is directly pushed or pulled by the float's movement. More advanced versions may use magnetic reed switches or optical sensors.

The applications for úszókapcsolókat are widespread. They are commonly found in sumps, septic tanks, water heaters, washing machines, and industrial tanks to prevent overflow or dry running of pumps. They can also be used to maintain a specific liquid level in various processes. The simplicity and reliability of float switches make them a cost-effective solution for many level control needs. Installation typically involves suspending the switch in the liquid at the desired activation point.
