An integral volume control and switch assembly comprising a resilient conductive member serving for switching between a first and second switch state and a resilient tactile member serving for providing a user with a tactile feedback upon change of switch state. The resilient tactile member and the resilient conductive member are formed by separate members.

In addition, it is possible to adjust angular position of the rotatable member where switch function and tactile feedback occurs. Preferably the resilient tactile member and the resilient conductive member are spatially separated along a rotational axis of the rotatable member. The assembly according to the invention is suitable for hearing aids.
