A "float switch" is a mechanism widely used for automatic control and alarm of liquid levels in water supply and drainage tanks, as well as oil tanks, by capturing the movement of a float that floats on the liquid surface and follows fluctuations in the liquid level. The same device is used for both water supply and drainage, making it easy to handle by moving the rod position to the right side for water supply and to the left side for drainage. The center of the float has a hole for the rod to pass through, allowing the float to be mounted on the rod. Limiters for both high and low limits can be installed at any position on the rod to create changes in the liquid level. The high liquid level operates the lever through the buoyancy of the float, while the low liquid level operates the lever through the weight of the float, turning the contacts built into the housing ON and OFF. 【Features】 ■ Easy to handle ■ Operates the lever through the buoyancy and weight of the float ■ Explosion-proof options available *For more details, please download the PDF or contact us.
