Interface assembly and method for manufacturing interface assembly

An interface assembly, comprising

• a functional multilayer structure comprising:
• a first substrate,
• a molded material layer on a first side of the first substrate, wherein the molded material layer defines a groove, a hole, or a through-hole, and
• a sensor arrangement comprising at least one sensor, wherein the sensor arrangement is arranged at least partly embedded into the molded material layer;
• and
• a movable member being movable relative to the functional multilayer structure and at least partly extending into the groove, the hole, or the through-hole, wherein the movable member comprises at least one detection portion;
• wherein
• the sensor arrangement and the at least one detection portion are mutually arranged so that a position or a change of position of the movable member is detectable by the sensor arrangement based on a position or a change of position of the at least one detection portion relative to the sensor arrangement.
