An inhaler device including an inhaler canister 110 having a canister body 112 for containing a medicament, the cannister 110 being actuatable to deliver a dose of medicament; a casing 120 at least partially housing the canister; first switch means 128, 140, 150 for detecting when the canister body is in the actuated position relative to the casing; and an electronic counter 164, in which a count is storable, the count being derived from the number of actuations of the canister 110 detected by the first switch means 128, 140, 150; wherein the first switch means include first 140, 150 and second elements 128 located on the canister 110 and casing 120 respectively, the first switch means 128, 140, 150 being triggerable by relative movement of the first 140, 150 and second elements 128 without physical contact between the said elements. The switch means may comprised rib 128, transmitter 140, and receiver 150, wherein relative movement of the canister and housing causes rib 128 to be inserted between transmitter 140 and receiver 150 to block the signal. The transmitter 140 may be an LED which emits infra-red. |
