ABSTRACT:
A rotational body supported in a housing of the apparatus carries an angle indication marker, which serves as a signal trigger of a signal transducer secured in a positionally fixed manner relative to the housing of the rotational body. The signal transducer has a transducer body axially displaceably disposed in its transducer housing. This body is displaceable in the direction of its longitudinal axis in order to actuate a first contact switch, and is provided inside its other end face with a switch contact, cooperating with the angle indication marker, of a second contact switch. After the actuation of both contact switches, the angle indication marker is located in a predetermined rotary position, which is indicated in the associated test circuit and serves in particular to ascertain the supply onset position of the drive shaft of a fuel injection pump for internal combustion engines.
