ABSTRACT:
A sensor switch for controlling the fill level of granular material filled into a container in which the sensor may either be mounted adjacent a fill path of the container or at a separate location. The sensor includes an elongated arm pivotally attached to a bracket for operating a switch located within the bracket. The sensor may be adjustably mounted on an elongated, remote support member mounted either to the side walls or to the top of the container. The sensor may have three operating positions including an initial position, an actuated position in which the arm actuates the switch, and a third position in which the arm releases the switch.
