[0002] Plastic float switches are common water level control devices widely used in various water tanks, water towers, and water supply systems. They sense changes in water level by the up-and-down movement of a float, thereby controlling the start and stop of the water pump. This device is widely popular due to its simple structure, low cost, and ease of use.

[0003] A Chinese patent discloses a float-type water level control switch, in which the lower end of a vertically downward connecting shaft is connected to a float, and a movable connection is maintained between a horizontal connecting shaft and a vertically upward connecting shaft. The upper and lower ends of the outer cylinder have reverse threads, with the lower end of the vertically upward connecting shaft corresponding to the threaded hole at the upper end of the outer cylinder, and the upper end of the vertically downward connecting shaft corresponding to the threaded hole at the lower end of the outer cylinder. However, its transmission is inaccurate, resulting in a large precision error. Utility Model Content
