Aerosol-generating device with button arrangement having a membrane

An aerosol-generating device, comprising:

• a housing having an outer surface, an inner surface, and a through-hole connecting the outer surface and the inner surface;
• a button at least partially arranged in the through-hole;
• and
• a membrane fixed to the housing and extending across the through-hole,
• wherein a form-fit is provided between the housing and the button, and
• wherein the form-fit is configured to retain the button in the through-hole against the button falling out of the through-hole towards an outside of the aerosol-generating device.

A method for actuating a switch of an aerosol-generating device, the method comprising the steps of:

• moving a button from a resting position towards an inside of the aerosol-generating device into an activated position, wherein the button is at least partially provided within a through-hole of a housing of the aerosol-generating device;
• deforming a membrane of the aerosol-generating device by the movement of the button;
• actuating a switch by the movement of the button, the switch being provided on an opposite side of the membrane than the button;
• and
• retaining the button in the through-hole against the button falling out of the through-hole towards an outside of the aerosol-generating device by a form-fit provided between the housing and the button.
