Abstract

An electrical device arranged to display the status of said device on a flag significantly larger than the relative movements of any components of said device. In an envisaged embodiment of this invention, this is achieved by arranging two surfaces in close proximity, parallel to one another; means are provided for moving the two surfaces relative to one another. The first of said surfaces has parallel slits therein, of equal dimensions and in the same arrangement to strips on the second of said surfaces, such that said strips can be viewed through said slits. A further set of strips is interdigitated with said first set of slits, such that said second set of strips can be viewed when said first surface is moved to a different location relative to said second surface. The two sets of strips both comprise different images.
