The ornamental design for a belt conveyor material flow indicator switch, as shown and described. |
FIG. 1 is a rear perspective view of a belt conveyor material flow indicator switch, showing my new design;
FIG. 2 is a front elevational view thereof, the rear elevational view being a mirror image of the figure shown;
FIG. 3 is a top plan view thereof;
FIG. 4 is a bottom plan view thereof;
FIG. 5 is a right side elevational view thereof;
FIG. 6 is a left side elevational view thereof; and,
FIG. 7 is a right side elevational view thereof, similar to FIG. 5 but with the hinge plates and plungers in slightly angularly elevated position under upwardly urgency of the expansion springs in unloaded condition of the belt conveyor and with resultant separation of the right hand plunger from the microswitch.
