A mobile communication terminal having a jog key is provided to locate a coil spring in an upper part of a dome switch by using a coil spring support, thereby shortening overall length of the jog key, consequently width of the terminal can be reduced. A jog key(100) comprises as follows. A lever(110) rolls in front/rear direction by being exposed to an outer side of a mobile communication terminal, and a mobile body(130) rolls along the lever in connection with the lever. A housing(180) is mounted with a dome switch(170), and wherein the mobile body is set. A coil spring support(160) is set in an upper part of the dome switch, and wherein grooves(161) in which coil springs(150) are to be located are formed in parallel. A pusher(140) is located as neighboring on the dome switch by piercing through the mobile body and the coil spring support, and pressurizes the dome switch by a pressing action of the lever.
