Electrical addressing devices of the generic type are mainly used for addressing bus subscribers in data transmission systems or electrical consumers in switching or control systems. They are usually installed in externally accessible module elements of these systems to allow adjustment of the address or maintenance, the address setting is often done by means of electrical components such as rotary encoder or dip switches, which are housed on printed circuit boards. To set the address code of the address to be set is usually a printed on the housing of these module elements number or a number sequence to select, in the case of DIP switches usually a binary number, and in the case of Drehcodierschaltern usually a decimal or hexadecimal number is set. The adjusting means themselves are usually designed as mechanical switches, dials, levers, buttons or the like.

US 3,818,155 discloses an electrical switching device with adjusting means, each on a first conductor plate are arranged, which is plugged into a connector which is connected to electrical conductors.

US 3,536,877 shows arranged on a first circuit board electrical adjustment means which are electrically connected to a second circuit board via a solder joint.

EP 0 312 282 A2 shows an encoder device with an electrical adjustment means on a first circuit board having electrical contact points to be connected to a motherboard.

The publication WO2010 / 054854A1 describes an electrical terminal module with an addressing option, which installed together with other electrical or electronic modules in control cabinets and secured by snapping onto a DIN rail. To execute an address function of this terminal module is equipped with an adjusting means for changing an electrical manipulated variable of a circuit arrangement. According to the WO2010 / 054854A1 can be made with such a device, a selection of switching positions to make, for example, an address setting or coding of participants of a bus system.

In such electrical addressing devices with rotary coding switches addressing is often possible only in the single-digit address range, so that only the setting of an address in the decimal range with the digits from zero to nine is possible. If the setting of a multi-digit address is required, then either a further adjusting means, for example a further rotary coding switch, must be used, or a dip switch bank with a plurality of dip switches must be used, in which case the address must be entered in binary code , which must be calculated accordingly beforehand. A quick input of the address code and a good readability of the set address is therefore not possible.

Furthermore, the document provides WO2010 / 054854A1 an electrical terminal module for installation in a cabinet with an addressing function, which has an electrical adjustable component with an adjustment means for entering a multi-digit address code.

However, such an addressing device is not externally accessible, for example, for maintenance or retooling, without the housing of the electrical terminal module must be opened. Furthermore, the addressing device is directly connected to the printed circuit board, so that the mechanical forces acting on the address adjustment are transmitted to the adjusting means directly on the electrical components of a printed circuit board, whereby they can be damaged. Conversely, vibrations occur on the printed circuit board, which act on the control cabinet periphery and thus on an addressing device, for example, caused by a controlled and addressed by the control panel system Motor drive, these vibrations are transmitted directly to the addressing device, which also carries the risk of failure. If such an addressing device must be replaced or retrofitted, this is often associated with considerable effort.
