Drug delivery device with electronics

An inhaler for delivering medication to a user, the inhaler comprising:

• a main housing comprising a mouthpiece and a yoke;
• an electronics module comprising a controller and a switch, wherein the switch is configured to, when actuated, cause the electronics module to change between power states;
• a slider configured to actuate the switch to cause the electronics module to change between the power states while the slider is in contact with the yoke, and configured to separate from the yoke after the electronics module changes between the power states;
• and
• a slider spring position on a surface of the slider, wherein the slider spring is configured to apply a force on the slider to cause an arm of the slider to press the switch and cause the electronics module to change between power states as the yoke moves downward.

An inhaler for delivering medication to a user, the inhaler comprising:

• a metering system configured to meter a dose of medication from a medication reservoir;
• an electronics module comprising a controller and a switch, wherein the switch is configured to, when actuated, cause the electronics module to change between power states;
• a mouthpiece cover configured to move between a closed position where the mouthpiece is covered and an open position where the mouthpiece is exposed, wherein the mouthpiece cover is configured to cause the metering system to meter the dose of medication from the medication reservoir when the mouthpiece cover is moved from the closed position to the open position;
• a slider configured to be in contact with the metering system when the mouthpiece cover is in the closed position, and configured to be separate from the metering system when the mouthpiece cover is in the open position;
• and
• a slider spring position on a surface of the slider, wherein the slider spring is configured to apply a force on the slider to cause an arm of the slider to press the switch and cause the electronics module to change between power states as the metering system moves to meter the dose of the medication from the medication reservoir.
