In the present embodiment, the use of the microswitch 71 is specifically described by taking the direct-pressing key 5 as an example. When the function corresponding to the direct-pressing key 5 needs to be started, the direct-pressing key 5 is pressed downwards first, the direct-pressing key 5 pushes the direct-pressing connecting piece 6 to slide downwards, and therefore the micro switch 71 which is in contact with the direct-pressing connecting piece 6 is pressed. The remaining micro switches 71 are turned on in the same manner, and will not be described again.
Since the direct push button 5 is mounted on the four-direction cover 2, when any one of the push portions 21 of the four-direction cover 2 is pushed, the direct push button 5 is inclined along with the four-direction cover 2, and the microswitch 71 corresponding to the direct push button 5 may be touched by mistake.
