DISPLAY DEVICE FOR AN ACTUATOR AND ACTUATOR FOR AN ARMATURE
First Claim
1. A display device for an actuator having at least one mechanical display element and a variable-speed gear unit, in particular a signal gear unit designed as a variable-speed gear unit, having at least two gears with different gear ratios, wherein a mechanical switching system is provided by means of which the different gears and/or gear ratios of the variable-speed gear unit may be selected and/or switched from the outside, even when an operational display device is installed in a housing, without intrusion into the housing and without opening the housing, and/or wherein the resolution of the display device and/or the motion of the at least one display element on the adjustment distance of a particular actuator to be displayed and/or of a particular fitting may be selectively adjusted.

Abstract
The invention relates to a display device (54) for an actuator having at least one mechanical display element (10, 11) and a variable speed gear unit, particularly a signal gear unit designed as a variable speed gear unit, having at least two gears with differing transmission ratios, wherein there is a mechanical switching arrangement with which the different gears and/or transmission ratios of the variable speed gear unit can be selected and/or switched even when the display device is mounted operationally ready in a housing without intervention into the housing and without opening the housing from outside, and/or wherein the resolution of the display device (54) and/or the movement of the at least one display element (10, 11) on the actuating path to be displayed of a respective actuator and/or a respective armature can be selectively adjusted. The invention furthermore relates to an actuator having a said type of display device (54).
