Vertical Float Type Level Switch SMC-7 Seires
Product descriptions
The electric contact switch operates as per the principle of magnetism, and the electric contact switch is normally "relay-off " position because of tension spring.
There is magnetic steel on the edge of Float's Rod, and this magnetic steel sticks to magnet installed inside the housing when the level goes up.
At this time, electric contact switch turns on because the switch designed to "relay-on" when the magnet sticks to magnetic steel of the Float s Rod. When the level goes down , on the contrary, the Float goes down and accordingly the magnetic steel on the Float s edge goes down.
Therefore, the magnetic steel detaches from the magnet and the switch is returning to "relay-off" position due to tension spring.
