Rotary Switch Working Principle

Making use of the motor to bring the blade revolving, when the medium rises to the blade position, the blade stops rotating because of the impediment of the medium, thus through the related control mechanism outpus open (on) or close (off) the contact signal; when the medium drops and leaves the blade, under the force of spring, the blade restores the beginning position to go on rotating and detect position change.

Features

? Compact structure, small and convenient;

? Zinc alloy shell, solid and reliable

? Imported motor, stable performance

? Detection of different mediums, many kinds of blades to choose

? Best choice for the detection used in small tank
