Device for command and indicating units, in particular an engine-room telegraph

摘要

A device for command and indicating units, in particular an engine-room telegraph, has a hand lever (4) which is arranged on a shaft (3) mounted in the housing wall. The shaft (3) is provided with a pointer (6) to which a scale (9) is allocated. The pointer (6) is mounted on the shaft (3) in such a way as to be displaceable in the direction of the pointer axis and is guided with a projection (11) in a guide groove (12) arranged parallel to the pointer plane. In this way, it is possible for the scale (9) to be made flat or otherwise curved in any manner. Increased reading accuracy can thus also be achieved in the end areas of the scale. <IMAGE>
