るのに必要な荷重を示すものである。Next, the operation of the configuration of this embodiment will be explained. First, in the state shown in FIGS. 1 and 2, when the sliding member 16 is pressed with a fingertip, the coil spring 15 is compressed by the downward movement of the sliding member 16, and the film becomes free below the coil spring 15. The pressing portion 15c moves downward. Further, the sliding member 16 moves down and the coil spring 15
When the film pressing portion 15c approaches the film 13, the slope portion of the moderation projection 16e of the sliding member 16 comes into contact with the locking portion peripheral portion 15b of the coil spring 15. When the sliding member 16 is further pushed, the sloped portion 16e is moved around the locking portion 15 of the coil spring 15 as shown in FIGS. 3 and 4.
Push b to the front. This extrusion is performed using the restoring force of the curved coil spring 15, that is, it is a moderate operation. During this time, the film pressing portion 15c of the coil spring 15 presses the contact point 1 of the film 13.
Press 3a to turn on the switch. Further, the relationship between the operating load and the amount of movement of the sliding member at this time can have the characteristics shown in FIG. In the figure, the horizontal axis represents the amount of movement of the sliding member 16, and the vertical axis represents the load required to move the sliding member 16 forward.

The sliding member 16 is pushed upward by the urging force of 5,
The locking portion peripheral portion 15b of the coil spring 15 moves upward along the slope portion of the moderation projection 16e of the sliding member 16. Also, the film pressing portion 15c of the coil spring 15
moves upward and returns to the original state shown in FIG.
