[0023] The utility model will be described in detail below in combination with the drawings and examples.

[0024] The utility model embodiment, please refer to Figures 1 to 5 A dustproof ship type switch, including switch shell 1, plug post 2 and switch button 3, the inside of switch shell 1 is hollow and is provided, plug post 2 is fixedly connected at the bottom of switch shell 1, and switch button 3 is rotatably connected in the cavity of switch shell 1.

[0025] The inner edge of switch shell 1 is provided with rectangular plate 9, and the two sides of switch button 3 are fixedly connected with a plurality of first protrusions 7, and the rectangular plate 9 is provided with a plurality of second protrusions 8 matched with the first protrusions 7;Switch button 3 and switch shell 1 are sealed by a plurality of first protrusions 7 and a plurality of second protrusions 8, and in the embodiment, the second protrusions 8 and the rectangular plate 9 are cross arranged, on the one hand, to facilitate sealing switch button 3, and on the other hand, not to affect the normal rotation of switch button 3 to open or close.

[0026] The detailed setting of the second protrusion 8 and the rectangular plate 9 is disclosed below, please refer to Figure 2 And Figure 3 A plurality of first protrusions 7 and second protrusions 8 are triangularly arranged, the first protrusion 7, the second protrusion 8 and the rectangular plate 9 are all silica gel materials, and in the embodiment, the triangularly arranged first protrusion 7 and the second protrusion 8 are closely sealed, so as to reduce the entry of external dust or water stains.

[0027] The detailed structure of how switch button 3 realizes rotation is disclosed below, please refer to Figure 2 And Figure 3 The two sides of switch shell 1 are provided with limiting holes 6, and the two sides of switch button 3 close to the limiting holes 6 are integrally provided with limiting posts 10, the limiting posts 10 are rotatable in the limiting holes 6, and the limiting holes 6 and the limiting posts 10 are mutually adapted.

[0028] The maximum distance of switch button 3 rotation is limited, please refer to Figure 4 AndFigure 5 The left and right sides of the switch shell 1 are integrally provided with the card 4, the card 4 is fixedly connected with the moving plate 5 close to one side of the switch shell 1, recesses 11 are formed in the upper and lower surfaces of the moving plate 5; rectangular grooves 14 are formed in the left and right sides of the switch shell 1, a reset spring 12 is fixedly connected inside the switch shell 1, a sliding block 13 is fixedly connected to the side of the reset spring 12 away from the switch shell 1, the end of the recess 11 is arc-shaped, the size of the rectangular groove 14 and the moving plate 5 is adapted to each other, the side of the sliding block 13 in contact with the recess 11 is arc-shaped, in this embodiment, a damping rod is arranged inside the reset spring 12, so as to prevent deviation when the reset spring 12 is compressed or relaxed, and the end of the recess 11 and the side of the sliding block 13 are arc-shaped, so as to facilitate unlocking of the sliding block 13 from the recess 11.

[0029] Working principle: first, the switch shell 1 is held by the staff and pressed, so that the plug post 2 is inserted into the required position, then during pressing of the switch shell 1, the two groups of cards 4 will first contact and press the mounting hole, so that the two groups of cards 4 are close to the direction of the switch shell 1, then the two groups of cards 4 will drive the moving plate 5 to slide in the rectangular groove 14, when the moving plate 5 slides the maximum distance in the rectangular groove 14, the side of the moving plate 5 away from the card 4 will leak out to the inner cavity of the switch shell 1, so that when the staff presses the switch button 3, the movement range of the switch button 3 will be limited, preventing excessive pressing of the switch button 3 from causing the switch button 3 to be unable to be normally used;
