Features Electric Switch Signal Output: Transforms the state of liquid in the pine into an electric switch signal, providing real-time monitoring and control over water . Versatile Switch Control: Can be utilized for both water outlet power on and water outlet power off scenarios, offering flexible and customizable functionality for different water systems. Fast Electric Water Heater Compatibility: Ideal for controlling water in fast electric water heaters, ensuring efficient and safe . Filter Replacement Prompt: Suitable for self-priming water purifiers and those in areas without tap water, providing timely reminders to replace filter cores for consistent water quality. Easy Installation: Features a G1/4in male thread connecting port for effortless installation and connection, ensuring convenience and simplicity. Features: 1、Output the state of the liquid ing or stationary in the pine as an electric switch signal 2、Depending on the switch control method, it can be used for two ways: water outlet power on or water outlet power off 3、Can be used for water control of fast electric water heaters 4、Suitable for prompting replace the filter core of self-priming water purifiers and water purifiers in areas without tap water 5、The connecting port is G14in male thread, easy to install and connect Specification: Item Type: Water Sensor Switch Model: fs-1/4-1 Connecting Thread Size: Male thread G1/4in Material: PP Working Voltage: DC0-110V Working Current: 0.5-1A Maximum Withstand Voltage: ≤0.2Mpa Maximum Temperature Resistance: 85℃ Medium Specific Gravity: 0.7 Working Principle: When there is water ing in the water switch, the magnetic core in the water switch is pushed by the water to cause displacement, and the magnetic core displacement drives the magnetic source to generate a magnetic control action so that the water switch outputs a "on" signal. This signal is input to the device control system, and the control system is used to realize the control function. When the water is less than the starting , the water switch outputs an "off" signal. The control system produces the opposite control effect Package List: 1 x Water Sensor Switch Note: This product is intelligently installed vertically.
