A rotating paddle, being loaded by sediments in a tank, activates a limit switch and brings contact output and motor rotation to a halt at the same time. With no load by sediments, the motor resumes rotation. When the paddle is overloaded or suffers strong shock, a clutch system prevents the motor from being broken by letting out excessive load and shock.
