Abstract
The invention concerns a display for a medical injection device (1) wherein an injection dose is pre-selected by rotating an operating head (2) and then is administered by axially displacing said head. Switching devices (7, 8) are apposed to the operating head (2) to actuate switches (7, 8) of which the switch positions are transmitted to a printed circuit board (13). The printed circuit board (13) preferably contains a processor, so that values such as set injection dose, the sum of administered injection doses etc. and signals concerning operational states are shown on a display system (15).
