As shown in Fig. 10 and Fig. 13, the button 2 is penetrated in the button hole 111 and the top is exposed from the housing 1. The outer wall of the button 2 is provided with four centering convex keys 21 which equally divide the circumference, and the lower end surface of the button 2 is provided with There are eight triangular teeth 22 formed on the tooth surface, the lower end surfaces of the four centering convex keys 21 and the four triangular teeth 22 spaced apart from the lower end surface of the button 2 respectively have a tooth surface, and the tooth tips of the centering convex keys 21 are located on the opposite side. On the center line of the convex key 21 , a positioning post 23 is arranged at the center of the top wall of the inner chamber of the button 2 .

The first contact cylinder 4 includes a cylindrical main body 41 and an annular outer flange 42 on the upper end of the main body. The first contact cylinder 4 is placed on the first spring 6 by contacting the upper end of the first spring 6 with its annular outer flange 42 , the cylindrical main body 41 is located in the first spring 6 , and the bottom of the cylindrical main body 41 is located directly above the second spring 7 .

As shown in Figure 11 and Figure 12, the rotating gear ring 3 is arranged between the first contact cylinder 4 and the button 2, and the rotating gear ring 3 abuts against the button 2 or the button hole 111 under the pushing action of the first spring 6, and rotates. The gear ring 3 includes an upper pivot 31, a gear ring body 32 located in the middle and a lower pivot 33. The upper pivot 31 is inserted into the button 2, and the lower pivot 33 is inserted into the first contact cylinder 4. The outer wall of the gear ring body 32 is provided with Four offset protruding keys 34 that equally divide the circumference, and the upper end surface of the toothed ring body 32 is provided with tooth surfaces to form eight triangular teeth 35, and the upper end surfaces of the four offset protruding keys 34 are respectively connected to the four sides of the upper end surface of the toothed ring body 32. The three spaced triangular teeth 35 share a tooth surface, and the tooth tip of the offset convex key 34 deviates from the centerline of the offset convex key 34 . The upper end surface of the upper pivot 31 of the rotary gear ring 3 is provided with a counterbore 36, and the center of the counterbore 36 is provided with a positioning column 361, and the counterbore 36 is equipped with a button return spring 37, and the upper part of the button return spring 37 is set on the button 3. On the positioning column 23 of the inner cavity top wall, the lower part is sleeved on the positioning column 361 .

The offset convex key 34 and the centering convex key 21 are accommodated in the keyway 114 of the button hole 111 and can move up and down in the keyway 114. When the offset convex key 34 is at the highest position in the keyway 114, the second There is a gap between the bottom of a contact cylinder 4 and the second spring 7, and the thickness of the gap is half of the height difference of the offset convex key 34 in the key groove 114. When moving down half in the key groove 114, the offset When the convex key 34 leaves the keyway 114, it can rotate in one direction under the guidance of the first slope 115 and the second slope 116 on the lower end surface of the keyway 114, because the first slope 115 and the second slope 116 form a recess 117 at the intersection , the concave position 117 can be used for positioning the offset convex key 34 . The thickness of the gap must be less than the height difference of the offset protruding key 34 in the keyway 114, generally between one-third and two-thirds of the height difference.

As shown in Figure 13, when there is no pressure on the button 2, under the elastic force of the first contact spring 6, there is a gap between the first contact cylinder 4 and the second spring 7, and the button switch is in the off state ( static state), no signal output.

When the button 2 is pressed, the first contact cylinder 4 moves down until the bottom of the first contact cylinder 4 is in contact with the top of the second spring 7 , due to the gap between the first contact cylinder 4 and the second spring 7 It is less than the downward movement length of the offset convex key 34 in the keyway 114, so when the first contact cylinder 4 is in contact with the second spring 7, as shown in Figure 13, the offset convex key 34 of the rotary gear ring 3 is still in the keyway In 114, the rotating gear ring 3 cannot rotate, so the pressure of the button 2 is removed, and the first contact cylinder 4 moves upward and returns to the original position (low position) of the keyway 114 under the action of the first spring 6, and is disconnected from the second spring 7 , which produces an instant trigger effect.

And when the button 2 continued to move down, the offset convex key 34 moved out in the keyway 114, because the tooth tip of the centering convex key 21 was positioned at the center line of the centering convex key 21, and the tooth tip of the offset convex key 34 deviated from the center line. Set the center line of the convex key 34, so there is a phase difference between the triangular teeth 22 on the button 2 and the tooth tips of the triangular teeth on the rotating gear ring 3. Under the cooperation of the triangular teeth 22 and the triangular teeth 35, the rotating gear ring 3 can be driven Make one-way rotation one position and turn over the crest of the first oblique wave 115 and fall on the first oblique wave 115, but cannot return to the notch of the keyway 114. At the same time, under the pushing action of the first spring 6, the bias The protruding key 34 moves along the first slope 115 toward the wave bottom, and is finally locked at the concave position 117 at the intersection of the first slope 115 and the second slope 116, and cannot be rotated. At this time, the first contact is formed. The barrel 4 is in long contact with the second spring 7, so that the button switch is in a long conduction state.

If the button 2 is pressed down again to make the bias convex key 34 move down to the crest of the second oblique wave 116, under the pushing action of the first spring 6, the bias convex key 34 of the rotary gear ring 3 moves along The second oblique wave 116 moves to the notch of the next keyway 114 in the direction of its wave bottom. At this time, the pressure of the button 2 is removed, and the offset convex key 34 of the rotating gear ring 3 will move upward into the keyway 114. The first contact The barrel 4 is disconnected from the second spring 7 and returns to a static state.

It can be seen that when the button 2 is pressed continuously, the rotating gear ring 3 will rotate cyclically in one direction, which is the same as the horizontal direction of the first ramp wave 115 or the second ramp wave 116 from the wave top to the wave bottom. correspond.

To sum up, this button switch can output two states of conduction and instant trigger, and use the cooperation between the convex key and the keyway and the cooperation between the triangular teeth and the triangular teeth, so that the button can be pressed up and down smoothly. The second spring is pressed and the second spring is pressed. Once the contact cylinder is in contact, the contact is more stable and reliable.
