The connecting rod float level switch operates using magnetic force without mechanical connectors, making it simple and reliable to operate. When the float switch is used to float the measured medium, the float drives the main body to move, and at the same time, the magnet on the other end of the float controls the magnet on the switch action rod.

 
Install one or more magnetic spring switches inside a sealed metal or plastic tube, and then thread the tube through one or more hollow floating balls with circular magnets inside. Use a fixed ring to control the floating balls and magnetic spring switches to move up and down within a certain range. Use the magnet inside the float to attract the contact of the magnetic spring switch, producing the action of opening and closing.
