 Display the position legibly by means of a contact device at all shaft entrances. For this purpose, in order to close the required circuit at the desired point, suitably attached contact rollers have been used, which move along slide springs or contact plates.



  This type of circuit closure can only be used for low depths and low driving speeds. These contact rollers are less useful, especially for shafts in mining operations, because at the high speed of travel due to the high number of revolutions of the contact rollers, they are very
