The CSH-L20-U Mechanical Float Switch by CSH is an essential accessory for maintaining optimal water levels in various applications, such as sump pits, irrigation systems, and water storage tanks. This switch is designed with a durable and reliable mechanical float mechanism, making it a commonly used choice for industrial and residential applications.
The CSH-L20-U switch is a normally closed (NC) float switch, meaning that it completes an electrical circuit when the float is submerged in water. Once the water level drops below the desired mark, the float rises, opening the switch contacts and breaking the circuit. This mechanism ensures efficient and automatic water level control, preventing potential damages caused by water overflow or low water levels.
The float switch is designed with a high-quality, corrosion-resistant stainless steel construction, ensuring a long service life even in harsh environments. The switch body is also made from a durable, UV-resistant plastic material, further increasing its durability and resistance to external elements.
The CSH-L20-U Mechanical Float Switch is designed for water levels between 0.25 and 10 feet (0.08 to 3 meters), with a maximum voltage rating of 125V AC or 30V DC. It features a 1/2" NPT threaded connection for easy installation and can be used with various types of tanks and containers.
This float switch is an excellent choice for applications where continuous water level monitoring and automatic control are essential. It is easy to install, maintain, and provides reliable performance, making it a cost-effective solution for a wide range of applications.
In summary, the CSH-L20-U Mechanical Float Switch is a durable and reliable water level control solution designed for various applications. Its mechanical float mechanism ensures efficient and automatic water level control, while its high-quality construction with corrosion-resistant materials ensures a long service life. The switch's easy installation and versatile voltage and water level specifications make it an ideal choice for a wide range of applications.
