A multikey switch circuit for a mobile communication terminal is provided to accurately recognize the input of three or more multikeys by additionally arranging a transistor between switches of each line of a key matrix, thereby improving reliability of the product. A multikey switch circuit for a mobile communication terminal comprises the followings: a plurality of switches(SW1~SW6) which are arranged on each line of a key matrix; and a plurality of transistors(Q1~Q4) which are separately connected between switches of the each line and prevent the malfunction of input of the three or more multikeys. The switch is a PNP-type transistor.
