TILT SENSOR AND A BIN LEVEL SENSOR USING THE TILT SENSOR A device for detecting the filling of a storage bin with grain or similar materials comprises a tilt switch in the form of an elongate tubular body with an electrical switch as an upper part of the body. The electrical switch includes a lower dish shaped conductor on which a ball rolls so that it is normally centred when the axis of the body is vertical. An upper conductor is of inverted dish shape so that as the ball rolls toward the side of the body when the body is tilted, the ball engages both conductors to provide electrical connection for actuating a warning device. Mounting brackets are shown one of which uses a magnetic engagement with the bin wall and both of which provide vertical adjustment of a cable on which the tilt switch is suspended.
