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.
Low price dual ball float level switch is composed of magnetic spring switch and floating ball, vertical mounted, contact form SPST 1NO/ 1NC, contact power rating 50W, optional materials of stainless steel or plastic. This double ball level sensor is used for detecting the position of the liquid level.
