Sliding assembly for mobile or portable terminals, comprising: a plane first main part; a plane second main part slidably connected to the first main part, the second main part being spring-loaded by a first elastic module adapted to urge the first and second main parts apart from each other, the second main part further comprising a protrusion extending towards the first main part, the sliding assembly further comprising a locking element in the first main part with a recess arranged to cooperate with a first elastic module, such that the locking element is urged against the protrusion, the second main part being arranged to cooperate with the first elastic module, such that the protrusion is urged against the locking element, the second main part of the sliding assembly thereby being held in a center position, wherein the sliding assembly further comprises an actuator arranged to overcome an elastic force exerted by the elastic element onto the locking element when being subject to an outside force, thus releasing the engagement between the locking element and the protrusion and bringing the second main part into a first end-position due to the elastic force of the first elastic module. According to a second embodiment, the sliding assembly may comprise a guide track cooperating with a stop pin included in the second elastic module.
