A first (5) of the indicators and a first pipe (1) form part of an angular position indicating moving part (MR1) carrying a plate (9) co-operating with a first sensor (11) for generating a position signal for said indicator as a result of discontinuities in the material of said plate.A second display indicator (6) coaxial to said first indicator is coupled to a second angular position indicating moving part (MR2). The latter, which is mounted at a distance from the first moving part, is in a meshing relationship with a second pipe (2) carrying said second indicator. This second moving part carries a second plate (18) co-operating with a second sensor (20), for generating a position signal for said second indicator as a result of discontinuities in the material of said second plate.The plates (9, 18) and the sensors (11, 20) can thus be arranged respectively side by side thus reducing the height to the superposition of one plate and one sensor only to indicate independently the angular positions of the first and second indicators.
