PROBLEM TO BE SOLVED: To provide an operation switch device by which switching operation can be easily performed by a touch system. SOLUTION: In the operation switch device 10 having a push-button switch 13 on a part of an operation board 11, ultrasonic vibration pieces 17, 18 are arranged around the push-button switch 13 on the back surface 11b of the operation board 11. The friction resistance felt when touching the peripheral part of the push-button switch 13 on the surface 11a of the operation board 11 is sharply reduced by driving the ultrasonic vibration pieces 17, 18. As the touch of the surface 11a of the operation board 11 around the push-button switch 13 is different from that of another part when an user touches the operation board 11 in order to operate the push-button switch, the user can easily recognize the area where the push-button switch 13 is located.
