<P>PROBLEM TO BE SOLVED: To provide a technique effective for improvement of operability during switch operation, in a switch device provided on a steering wheel for vehicle steering. <P>SOLUTION: In this steering device with a horn switch device 120, when output voltage from a piezoelectric film 121 becomes a preset rated value due to deflection operation of a piezoelectric film 123 during press operation of a pressed member 121, a control part detecting the output voltage from the piezoelectric film 123 outputs a control signal to a horn unit. When output voltage from the piezoelectric film 123 is deviated from a rated value due to deflection release operation of the piezoelectric film 123 at the time of release of the press operation, the control part stops the output of the control signal. <P>COPYRIGHT: (C)2008,JPO&INPIT |
