POSITION INDICATOR_FOR A MOTOR DRIVE

摘要

The invention relates to a motor-drive position indicator for actuating a sequence shift, a change-over switch or a moving coil. To achieve this, a first circular scale is provided with symbols arranged thereon. Said symbols are allocated to each individual switching stage involved when changing from one motor-drive working position to another. The first scale is swept by a first pointer which rotates at 360~ each time switching occurs. A second circular scale is also provided with symbols arranged thereon. Said symbols are allocated to each possible working position of the sequence shift or other. The second scale is also swept by a pointer. The second pointer performs a rotational movement around an angle corresponding to the distance between two adjacent symbols on the second scale each time that switching occurs. Trailing pointers are arranged on both sides of the second pointer in such a way that one of them is pulled along according to the direction of rotation when the second pointer rotates. Both trailing pointers thus indicate the actual control range which is switched.
