Abstract: A combined roller and push switch assembly includes a substantially hollow wheel-like roller member being displaceable from an initial position to a displaced position. The combined roller and push switch assembly further includes a member for returning the roller member from the displaced position to the initial position, the returning member is a resilient member being at least partly encircled by the roller member, and a coding member for detecting rotation of the roller member in relation to an associated frame. In particular, the combined roller and push switch assembly further including a switch for indicating when the roller member is in the displaced position, the switch being at least partly encircled by the roller member.

Abstract: The present invention concerns a lifting device which is configured to be coupled mechanically to a given telephone apparatus, said telephone apparatus having a handset and a fixed part, and whereby the lifting of the handset activates a switch in the telephone apparatus. The lifting device comprises a movable element which is configured to be in connection with the handset and lift the handset by means of a drive unit which brings about a movement of the movable element. The lifting device also comprises a bracket which is configured to be placed on the telephone apparatus in between this and the handset, under which the movable element is housed in a movable manner in the bracket.
