{"Type": "Float Switch", "Working Principle": "A float switch consists of a float attached to an arm, which moves up and down based on the level. When the float rises or falls, it activates or deactivates the switch."n{"Type": "Vibrating Level Switch", "Working Principle": "This type of switch uses the vibration created by a magnet attached to the switch housing and a sensor to determine the level. When the liquid level changes, the vibration frequency changes accordingly, activating or deactivating the switch."n{"Type": "Ultrasonic Level Switch", "Working Principle": "These switches use ultrasonic waves to measure the level. The time it takes for the waves to travel from the sensor to the liquid surface and back is used to calculate the level."}
