A metered dose inhaler () for dispensing aerosol doses comprises an actuation housing () adapted to receive a canister (). The canister () is configured to move from a rest position to an activation position in which a valve () of the canister (), positioned at a valve end () of the canister (), is depressed against a bottom portion of the actuation housing such that an aerosol dose is released. The inhaler () further comprises a mechanical dose () 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 () comprises a triggering unit () for triggering at least one electrical switch () when the canister () is moved from the rest position to the activation position whereby an electrical signal is generated. Also part of the inhaler () is a processing unit for processing the signal generated by the switch () upon being triggered.

Inhaler

A dose counter for a metered dose inhaler has an activation valve at a valve end of the metered dose inhaler. The dose counter includes a housing having a first end and an opposing second end. The first end receives a metered dose inhaler valve end, and the second end defines a cavity. An actuation detection assembly in the cavity includes an actuation detection element on the second end of the housing, and an activator element in the cavity of the housing. The activator element is configured to move between a first position in the cavity in which the activator element is spaced apart from the actuation detection element on the housing by a gap and a second position in which the activator element cooperates with the actuation detection element so that the actuation detection element generates an actuation signal.
