KISAN This Heavy-Duty Pressure Switch is designed to provide automatic and accurate pressure control for air compressors and water pump systems. The switch activates the motor when pressure drops below the set limit and automatically shuts it off once the desired pressure is reached, protecting equipment from over-pressure damage and improving energy efficiency. The switch features a strong ABS enclosure that resists impact, dust, and environmental wear, while the internal components are made from high-grade metal and copper contacts for consistent electrical performance. The adjustable pressure mechanism allows users to customize pressure limits easily, making it suitable for both residential and industrial applications. Whether you are upgrading an existing system or installing a new one, this pressure switch offers reliability, safety, and durability you can trust.
