Movement Explanation
When the float down to the D position, in the position between D=3±1mm, the reed switches will be closed. Float ball reverses the opposite action.

Tips for using the float liquid level switch
- Handle gently because the inside of the float level switch is a dry reed pipe which is fragile.
- The temperature use of the plastic should be less than 80℃, and the stainless steel should be less than 150℃。
- Avoid vibration, magnetic field or over the maximum temperature for a long time in the use environment.
- Avoid to use this float sensor for the liquid that is too viscous.
- Remove the dirt on the float switch regularly, the clean period depends on the medium.
