Rotary level switch is connected with a clutch by the synchronous motor drive shaft. When the blade is not in contact with the material, the motor maintains normal rotation. When the blade is in contact with the material causing some resistance, the motor will stop its rotation. This give a contact signal and allows the mechanism of a switch to be present.
