The conductive surface swings relative to contact with a third pin to realize the on and off control of the indicator light.

[0033] The following is a detailed description of the specific implementation of the utility model in conjunction with the accompanying drawings:

[0034] In the description of the present invention, it should be understood that the terms "upper", "lower", "bottom", "top", "front", "back", "inside", "outside", "left", "right", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0035] The utility model discloses a three-speed push button switch, including a switch base 1, a button 2 hingedly arranged on the switch base 1 (the button 2 is most preferably provided with a hinge shaft, and a hinge hole is provided on the switch base 1, and the hinge can be hinged by cooperating with the hinge shaft and the hinge hole), the switch base 1 is provided with a first pin 3 and a second pin 4 arranged on two opposite sides of the first pin 3, a conductive seesaw 5 is swingably arranged on the first pin 3, a push rod 6 for driving the conductive seesaw 5 to swing to communicate with the second pin 4 is provided at the bottom of the button 2, the push rod 6 swings synchronously with the button 2 and can be retracted relative to the button 2, and the button 2 is also provided with a push rod 6 for driving the push rod 6 to swing to communicate with the second pin 4. An elastic member 7 is positioned in the position (the elastic member 7 is most preferably a spring, and of course it can also be a spring sheet, which can not only meet the telescopic avoidance of the push rod 6, but also control the extension of the push rod to achieve a positioning effect). In the implementation case of the utility model, the button 2 is provided with a circuit board 8 that swings synchronously with it, the circuit board 8 is electrically connected to the first pin 3, and an indicator light 9 is provided on the circuit board 8 (it is most preferred that a load resistor can also be provided on the circuit board 8), a first conductive surface 81 is provided at the bottom of the circuit board 8, and a third pin 10 is provided on the switch seat 1 corresponding to the lower part of the first conductive surface 81. The swing of the button 2 can drive the first conductive surface 81 to be electrically connected to the third pin 10.

[0036] By adopting the above technical solution, when in use, the push button 2 can be pressed to drive the push rod 6 to swing. While the push rod 6 swings, it will push the conductive seesaw 5 to make it swing, thereby contacting the corresponding second pin 4, thereby realizing the switching of gears. At the same time, the first conductive surface 81 will be electrically connected to the third pin 10, thereby lighting the indicator light 9. The first conductive surface 81 swings relative to each other and contacts the third pin 10 to realize the on and off control of the indicator light 9. Its stability is relatively good, and the accuracy requirement is relatively low. It is also convenient for the installation of the indicator light 9 and the load resistor, so that the indicator light 9 is more stable and will not shake relatively when in use.

[0037] An elastic conductive sheet 20 is connected to the top of the third pin 10. The elastic conductive sheet 20 is spaced apart from the first conductive surface 81. When the conductive seesaw 5 swings to connect with the second pin 4, the first conductive surface 81 swings to contact with the elastic conductive sheet 20. The contact between the elastic conductive sheet 20 and the first conductive surface 81 can increase the contact area and achieve a soft contact effect, thereby avoiding damage to components during swinging.

[0038] The elastic conductive sheet 20 includes a contact end 201 in contact with the first conductive surface 81 and a connecting end 202 connected to the third pin 10. Both sides of the contact end 201 are bent to form an arc-shaped contact surface 2011. The connecting end 202 can be easily connected to the third pin 10 (the connecting end 202 is most preferably formed into a frame shape). The arc-shaped contact surface 2011 is used to contact the first conductive surface 81 to further prevent damage to the first conductive surface 81 and play a protective role. The structural layout is relatively reasonable.

[0039] A waterproof cover 30 is provided on the switch base 1 at a position corresponding to the button 2, so that the product has a waterproof function and is more practical.

[0040] The button 2 includes a button cover 21 and a button seat 22 (the button cover 21 can be a flat cover or a V-shaped cover. When a flat cover is used, the top of the waterproof cover 30 can be stuck on the button cover 21 to form a seal. At this time, the button cover 21 can be exposed. At this time, the waterproof cover is most preferably a split black PVC waterproof cover, while a V-shaped cover needs to cover the entire button cover 21, but the swinging feel of the V-shaped cover is relatively good. At this time, the waterproof cover 30 is most preferably a transparent cover). The button seat 22 has a built-in cavity 40, the circuit board 8 is arranged in the cavity 40, and the button cover 21 is covered on the cavity 40. The split button cover 21 and button seat 22 can facilitate the assembly of the circuit board 8 into the cavity 40.

[0041] The switch seat 1 is also provided with an elastic expansion piece 50 on the outside, and an anti-backward tooth 501 is provided on the top of the elastic expansion piece 50, which can prevent the switch from slipping out after installation, making it more stable when used, and will not slide relatively after being tightened by the elastic expansion piece 50, making it more stable during assembly.

[0042] The second pin 4 is also provided with a stationary contact 60 , and the conductive seesaw 5 is provided with a movable contact 70 for contacting the stationary contact 60 , so as to facilitate the conductive seesaw 5 and the second pin 4 to be connected.

[0043] A transition section 203 is provided between the connection end 202 and the contact end 201 for connecting the two into one. The transition section 203 is arc-shaped or inclined, which can facilitate the bending and deformation of the connection end 202 and improve the soft contact effect.

[0044] The push rod 6 and the elastic member 7 are both made of conductive materials. A second conductive surface 82 is also provided at the bottom of the circuit board 8. One end of the elastic member 7 abuts against the second conductive surface 82, and the other end abuts against the push rod 6. The push rod 6 abuts against the conductive rocker 5, which can avoid adding additional conductive wires and does not affect the normal operation of the button 2, achieving multiple goals at one stroke.
