Apparatus for providing information as to a plurality of conditions using a single air core gauge. Each condition being monitored controls a switch that in turn controls the energization of at least one winding, the magnetic fields generated by the windings forming a resultant magnetic field that controls the orientation of an indicia-bearing rotatable disc. When one or more windings are energized a lamp illuminates the indicia which the disc locates at a certain position so as to indicate the status of the condition which caused energization of the winding. A provision is also made to index the disc between a plurality of positions so as to advise of several conditions which may require attention at the same time.
