Directional errors arise when the control box is twisted relative to the installation being controlled since the controls on the control box no longer have their original meaning. A direction indicating mechanism is therefore provided which comprises an indicating member mounted within the control box and visible to an operator, which indicating member is held against rotation relative to the installation but is able to rotate relative to the control box itself. | |
