Abstract
The present invention relates to a medication delivery device for expelling set doses of medicament, the medication delivery device comprising a position determining arrangement for detecting absolute positions of a movably mounted member, such as a dose indicator barrel, relative to a housing of the medication delivery device. The position determining arrangement comprises a plurality of electrically conducting electrodes arranged on an outer surface of the movably mounted member, and a plurality of contacts members fixedly arranged relative to the housing of the medication delivery device. A first and a second contact member are arranged to follow a first path across the electrically conducting electrodes upon movement of the movably mounted member relative to the housing, whereas a third and a fourth contact member are arranged to follow a second path across the electrically conducting electrodes upon movement of the movably mounted member relative to the housing.
