Described is a display for a medical injector (1) in which the injection dose can be pre-selected by turning a control knob (2) and subsenquently injected by moving the knob (2) longitudinally. Resting against the control knob (2) in the injector are switching means (7, 8) which actuate switches (10, 11, 12) whose positions are transmitted to a circuit board (13). By virtue of the organization of the circuit board (13), which conveniently includes a processor, values such as the injection dose selected, the total dose already injected, etc., plus operating-status signals are output to a display unit (15). |
