A display instrument with two illuminated pointers, in which instrument the illuminated pointers () are supplied with light via a light splitter (). The latter has a frustum-shaped depression () so that a portion of the light is radiated in the axial direction and passes into the upper illuminated pointer (). A further portion is scattered radially at the generated surface () of the frustum () and passes into the lower illuminated pointer ().

In an electric motor intended to be fixed to a printed circuit board, provision is made for it to have at least one expanding dowel ( ), for it to be possible for the motor ( ) to be fixed to a printed circuit board ( ) by the expanding dowel or dowels ( ) being expanded, and by it being possible for the expanding dowel or dowels ( ) to be secured at least by a pin ( ).

A coil assembly has a coil form on which the coil winding is arranged as well as a method of contacting the coil assembly on a support member. The coil assembly is easy to produce and also permits electrical contacting, namely, the provision of electrical contacts between terminals of the coil and an external circuit in a simple and reliable manner. The coil assembly has a coil form on which two contact feet are arranged, the ends of the coil winding being fastened to the respective contact feet.

An electric motor has two exciter windings, independent of each other, on a stator, by which windings a resultant magnetic field can be produced. The motor includes a permanently magnetized rotor which has at least one pair of poles, the rotor changing its position as a function of the magnetic field, and the rotor being arranged axially on a rotor shaft. In the case of an electric motor which is of a small size and easy to manufacture, the stator is developed with several arms, and has an opening present at the center to receive the rotor. The individual arms are arranged around the opening and, there are, two pairs of opposite arms. The opposite arms are so bent towards each other so that, upon their receiving a respective exciter winding, they produce magnetic vectors which are perpendicular to each other.
