PROBLEM TO BE SOLVED: To provide a switch device having a structure for conducting between electrodes by low-load press operation, capable of securely conducting by the press operation, and securely maintaining non-conductive state in a non-pressed state. SOLUTION: A plurality of switch elements 6 are mounted on a printed board 5. The switch element 6 includes a fixed electrode 11 formed on a bottom surface of a reservoir part 10 formed on a surface of a fixed part 9, and is structured by accumulating nonconductive liquid 12 inside. The reservoir part 10 is closed by a closing part 13, and a movable part 8 is supported on a hole part 13a formed on the closing part 13 so as to move vertically. The movable part 8 is floated by the nonconductive liquid 12. The switch element 6 is protected by a protection sheet 7. The movable part 8 moves downward from a normal position by touch operation to the switch device 1, and a movable electrode 14 provided on a lower surface of the movable part 8 is in contact with the fixed electrode 11 and is conducted.
