Different types of switches are employed, some of which are as follows: A tum-table (see Fig. 6.6.4) is used for transferring a load from one roller conveyor to a sliding runway or to a perpendicular roller conveyor. This consists of a small length (equal or slightly smaller than the width of the main conveyor) of roller conveyor mounted on a frame which is fixed on a vertical shaft mounted on bearings. Once the load comes on base the turn-table, the turn table can be rotated (manually or by proper mechanism) to the desired and the load can be rolled over to the desired runway angle A hinged section (Fig. 6.6.4) is small section of the conveyor which is hinged at one end a with the famestand of the main conveyor. and can be lifted up to make a passage way through the conveyor line. An array of wheel rollers on swiveling heads (castor wheel) are used independently or as a part of a roller conveyor where it is necessary to move the load in many directions. Deflector is a flat or angle like section placed longitudinally over the conveyor making an angle (may be adjustable or fixed) with the conveyor axis. This acts as an obstruction to the movement of the load and deflects them to one side of the conveyor axis. Manipulator consists of one pair of deflectors to bring the loads at the middle section of the conveyor axis. Deflector or manipulator is used on idle conveyors and more commonly with powered roller conveyors with chain rope pushing facility
