  Since the urging force of the urging member 900 is applied to the first and second interlocking members 300a and 300b via the pedestal 500, the number of parts is small and the size can be easily reduced.

  In the first invitation mechanism 10a, when the first slider 400a returns to its initial position, the first concave portion 11a and the first convex portion 12a are fitted by the elastic force of the first contact 710a of the first variable resistor 700a. While moving, the first slider 400a is moved so as to be guided to the initial position immediately before moving to the initial position. Therefore, the error is absorbed while absorbing the manufacturing tolerance of the pedestal 500 and the first and second interlocking members 300a and 300b.

  Since the operation member 200 slides on the substantially convex inner bottom surface 311a of the bottomed guide groove 310a of the first interlocking member 300a, the total height of the product is suppressed even if the movement amount (rotation radius) of the operation member 200 is increased. Can be

  Since the operation member 200 does not penetrate the first interlocking member 300a, the strength of the first interlocking member 300a can be kept high, and the durability of the device can be increased.

  When the pressing force applied to the operation member 200 is transmitted to the metal dome 712c via the first interlocking member 300a and the pusher 800, the first interlocking member 300a functions as a "lever" and is applied to the operation member 200. Since a force smaller than the pressed force is transmitted to the metal dome 712c, a large change in load occurs when the metal dome 712c is pressed, and a high click feeling can be obtained.

  Therefore, even if the amount of movement (rotation radius) of the operation member 200 is increased, the overall height of the product is suppressed, the durability of the product is high, and the operation feeling of the push switch 700c is good.
