PROBLEM TO BE SOLVED: To provide a PDA being a portable device which can make downsizing the constitution in which a given fixed contact is selected from a plurality of fixed contacts and this selected fixed contact is switched over. SOLUTION: A first movable contact 10 having three mutually linked contacts 10a, 10b, 10c on a printed-circuit board is formed against a printed-circuit board 6 having a plurality of fixed contacts 7a-7d arranged in a row, and a pair of contacts 11, 12 that contact one of the fixed contacts 7a-7d and contacts 10a, 10b, 10c simultaneously are formed as a second movable contact 13, and these first movable contact 10 and the second movable contact 13 are moved along the row direction by a first movable part 9 and a second movable part 14, thereby variously switching over connection among the fixed contacts 7a-7d.
