2 is provided with a dust-proof filter 25 adhered to the rear surface by an adhesive tape or the like. Here, in the present embodiment,
Since the rear opening of the element case 22 is closed by the filter 25, it is possible to prevent foreign matters such as dust and dirt from entering the inside of the element case 22 from behind the element case 22. The filter 25 is made of a fluorinated fiber material (Teflon fiber material). By the way, the suction cup block 23 includes the suction cup 23b and the suction cup 23 described above.

Therefore, when the card pressing portions 51b and 52b formed by both legs of the arms 51 and 52 move away from the tip of the pressed portion 26a formed by both legs of the card 26, the suction force of the suction cup 23b to the suction target 24 gradually decreases. The suction force becomes weaker than the restoring force of the return spring 27, and the suction cup 23b separates from the to-be-adsorbed body 24.

That is, the pressing member 70 is
2, the card pressing portions 51b of the arms 51 and 52,
The card 26 moves forward (upward in FIG. 2B) after a predetermined time (hereinafter referred to as a delay time) from the time when the 52b leaves the pressed portion 26a of the card 26.
Therefore, the delay time can be adjusted by changing the air permeability and size (cross-sectional area and length) of the air permeable member 32, the material of the suction cup 23b, and the material of the to-be-adsorbed body 24. .

In this embodiment, the air permeable member 32

The terminal plates 63a and 63b have different fixed contacts 64a and 64b, respectively, and form different switch mechanisms in the switch body. The base end of a plate-shaped contact spring 70 is joined to the terminal plate 63c. Here, the contact spring 70 extends over the card member portion 26c of the card 26 of the delay element 20 through the notch groove (not shown) of the frame 21 described above, and has a movable contact 72 formed at the tip end thereof.
