Abstract
The present disclosure refers to a switch assembly for an electronic system of a drug delivery device. The switch assembly includes a chassis supporting a PCBA including at least a first electrical contact, a second electrical contact, a third electrical contact and a fourth electrical contact and a ring with a ratchet profile. The chassis moves axially relative to the ring from a first axial position to a second axial position during a first switch operation mode. The chassis and the ring are configured such that the ring rotates relative to the chassis during a second switch operation mode. The first electrical contact and the second electrical contact are arranged such that upon axial movement of the chassis towards the ring during the first switch operation mode, an electrical connection between the first electrical contact and the second electrical contact is closed.
