🛠Float switch is a type of level sensor, a device used to detect the level of liquid within a tank.
🛠The switch may be used to control a pump, as an indicator, an alarm, or to control other devices.
🛠One type of float switch uses a mercury switch inside a hinged float.
🛠Another common type is a float that raises a rod to actuate a microswitch.
🛠One pattern uses a reed switch mounted in a tube; a float, containing a magnet, surrounds the tube and is guided by it.
🛠When the float raises the magnet to the reed switch, it closes.
🛠Several reeds can be mounted in the tube for different level indications by one assembly.
