Claim 15:
16. A drug delivery device comprising:
a body;
a button assembly secured to the body, the button assembly comprising:
a button body forming a touch surface, a side surface, and an axially elongated member connected to the button body for energy transmission to a driven element of the drug delivery device, the side surface extending parallel to the axially elongated member, and
a support element, wherein the button body is movable in a longitudinal direction relative to the support element against a tension of a first resilient member retained by the support element and the button body,
wherein the button body and/or the axially elongated member comprises a shock deactivation mechanism configured to prevent movement of the button body relative to the support element or configured to prevent transmission of a shock force to the driven element of the drug delivery device caused by the shock force acting at the button body, wherein the shock force comprises at least one of a force component running transversal to the longitudinal direction of the button assembly and a force component running opposite to gravity,
wherein the shock deactivation mechanism is realized by the button body comprising a material composite with at least one first material component consisting essentially of a first material and at least one second material component consisting essentially of a second material different from the first material, the second material having a higher elasticity and/or plasticity than the first material, the first material and the second material at least partially forming the touch surface of the button body, the second material at least partially forming the side surface of the button body in a region opposite to a proximal end of the support element, and at least a portion of the touch surface being planar,
wherein the first material and the second material that at least partially form the touch surface of the button body are exposed along a rear surface of the button body such that the first and second materials are directly touchable.
