working principle:
The F4 side-mounted float ball level switch uses the principle of liquid buoyancy. When the float ball moves up and down due to buoyancy, the reed switch in the junction box is affected by the arm end magnet, and the "NO" and "NC" contacts are interchanged. The same principle is applied to the micro-switching device. The magnet and the arm-end magnet in front of the micro-switch are mutually exclusive to push the micro-switch, causing "NO" and "NC" action.
Features:
Optional "micro switch" or "reed switch" micro switch select operating temperature below 100 ° C
