A key assembly which is configured to provide improved click feeling to a user and an electronic device having the same are provided. The key assembly includes a key body of elastic materials and contact projections, each of the contact projections which is protruded and formed from the key body and presses a switch device spaced apart from the key body by a gap providing a certain interval, wherein the key body is installed such that a contact surface of each of the contact projections is in contact with and pushed back by a certain distance by a pre-loading force of the switch device.

Key assembly and electronic device having the same

A sliding module for a portable terminal which has a first housing and a second housing sliding on the first housing is disclosed, the sliding module slidably coupling the first and second housings. The sliding module includes a sliding plate mounted on a surface of the first housing; at least one guide rod mounted on a surface of the second housing and slidably coupled to the sliding plate, the guide rod being extended in the longitudinal direction of the second housing; at least one first guide rib formed on the sliding plate; and at least one second guide rib formed on the surface of the second housing, wherein the second guide rib is slidably engaged with the first guide rib, and maintains at least partial engagement with the first guide rib within a sliding range of the second housing.
