**float switch** (also known as a **water level controller switch** or **float sensor switch**). ### Details: * **Brand:** Gelzon (as seen on the label) * **Function:** This device is typically used to automatically control water pumps based on the water level in a tank or reservoir. * **Operation:** * When the water level rises or falls, the float moves accordingly. * The movement opens or closes an internal switch to either turn the pump **on** or **off**, preventing overflow or dry running. * **Cable:** The attached long red cable indicates it’s meant for submersion in water tanks or wells. Would you like me to explain **how to connect and use this float switch with a water pump**?
