Zusammenfassung:	A metered dose inhaler (1) for dispensing aerosol doses comprises an actuation housing (2) adapted to receive a canister (4). The canister (4) is configured to move from a rest position to an activation position in which a valve (7) of the canister (4), positioned at a valve end (8) of the canister (4), is depressed against a bottom portion of the actuation housing such that an aerosol dose is released. The inhaler (1) further comprises a mechanical dose (10) counter comprising an indicator member which is constructed and arrangement to undergo a predetermined count-indicating motion when an aerosol dose is released. Moreover, the inhaler (1) comprises a triggering unit (11) for triggering at least one electrical switch (12) when the canister (4) is moved from the rest position to the activation position whereby an electrical signal is generated. Also part of the inhaler (1) is a processing unit for processing the signal generated by the switch (12) upon being triggered.
