Description

Technical Field

[0001] This utility model relates to the field of electrical switch components, specifically to a push switch. Background Technology

[0002] Push-button switches are commonly found in various electrical appliances, used to control the connection and disconnection of common electrical circuits. Flashlights typically use push-button switches to control their lighting circuit. A typical push-button switch includes a button, a conductive component, and two terminals. Pressing the button actuates the conductive component, thus controlling the circuit's on / off state. However, existing push-button switches are prone to problems such as stiff or incomplete reset after releasing the button, affecting the user experience of flashlights and other electrical appliances. Therefore, improvements to the internal structure of push-button switches are needed. Utility Model Content

[0003] To address the problem of sticking and stiffness in existing push-button switches after rebound, this invention proposes a push-button switch that controls the movement of a movable contact via a button, thereby controlling the on / off state of the circuit. Furthermore, two elastic reset elements are provided between the movable contact and other components of the push-button switch, making the rebound of the switch more sensitive and smooth.

[0004] To achieve the above effects, the technical solution adopted by this utility model is as follows:

[0005] A push switch, the structure of which includes:

[0006] The device comprises a button, a housing, and a base. The base has a first pin and a second pin on both sides. Each of the first pin (4) and the second pin has a stationary contact. The housing contains a transmission component, a movable contact part, and two elastic reset components. The button is connected to the transmission component. The movable contact part is located below the transmission component and is driven by the transmission component to move. Each side of the movable contact part has a movable contact. The movable contact part includes a first position where the movable contact does not contact the stationary contact on the pin and a second position where the movable contact is in contact with the stationary contact on the pin. A first elastic reset component is provided between the transmission component and the movable contact part, and a second elastic reset component is provided between the movable contact part and the base.

[0007] Both the moving and stationary contacts are coated with a silver coating.

[0008] The button has a engagement tooth at its bottom, and the transmission component has a toothed engagement part at its bottom. When the movable contact part is in the second position, the engagement tooth and the toothed engagement part fit tightly together.

[0009] The base includes a transmission column, and the second elastic reset member is disposed above the transmission column.

[0010] The lower end of the movable contact part is provided with a conductive plate, which is used to connect the movable contacts on both sides.

[0011] The housing is provided with a buckle, and the base is provided with a slot. The housing and the base are connected by the buckle and the slot.

[0012] Each end of the base is provided with a pin limiting part, and the first pin and the second pin are respectively fixed in the pin limiting part.

[0013] The beneficial effects of this invention are as follows: the design of the transmission component and the moving contact portion improves the pressing feel of the push switch. The two elastic reset components at both ends of the moving contact portion also make the push switch rebound more smoothly during reset, reducing the stiffness of the push switch rebound and avoiding the problem of incomplete reset.

[0019] The present invention will now be described in detail with reference to the accompanying drawings.

[0020] like Figure 1 A push-button switch comprises a button 1, a housing 2, and a base 3 arranged from top to bottom. The housing 2 is connected to the base 3 via a latch 21 and a slot 32. The latch 21 and the slot 32 facilitate the assembly and disassembly of the housing 2 and the base 3.

[0021] like Figures 2 to 4The housing 2 contains a transmission component 7 and a movable contact portion 6. The transmission component 7 is located below and connected to the button 1. The movable contact portion 6 is located below the transmission component 7, and a first elastic reset component 8 is provided between the two. The movable contact portion 6 has a first moving contact 61 and a second moving contact 62 at both ends, and the first moving contact 61 and the second moving contact 62 are connected by a conductive plate 63 located at the bottom of the movable contact portion 6. The middle section of the movable contact portion 6 has a cylindrical cavity, and the middle section of the movable contact portion 6 is connected to the transmission column 31 of the base 3 by a second elastic reset component 9. The transmission column 31 provided in the base 3 makes the movable contact portion 6 more stable when resetting. In this utility model, the first and second elastic reset components are springs. The outer diameter of the first elastic reset component 8 is slightly larger than that of the middle section of the movable contact portion 6, and the outer diameter of the second elastic reset component 9 is slightly larger than that of the transmission column 31 and fits into the cavity of the middle section of the movable contact portion 6. The inclusion of two elastic reset components ensures a smooth reset of the push-button switch, guaranteeing that the moving contact 6 and button 1 return to their original positions before being pressed, thus preventing incomplete resets that could cause problems in subsequent use. It also reduces the stiffness during reset, extending the lifespan of the components.

[0022] The base 3 has a pin on each side, namely a first pin 4 and a second pin 5. The first pin 4 has a first stationary contact 41, and the second pin 5 has a second stationary contact 51. The midpoint of the first stationary contact 41 and the midpoint of the first moving contact 61 are on the same vertical line, and the midpoint of the second stationary contact 51 and the midpoint of the second moving contact 62 are on the same vertical line.

[0023] To make the push-button switch more sensitive and rapid, and to improve the conductivity of the internal circuit structure, in this invention, the surfaces of the first moving contact 61 and the second moving contact 62, which are provided with the movable contact part 6, and the first and second stationary contacts located on both sides of the plug, are all plated with a silver coating. The excellent conductivity of the silver coating makes the connection and disconnection between the contacts more rapid. The silver coating also avoids the problem of easy oxidation of the contacts after repeated use, thus extending the service life of the contacts.

[0024] like Figure 4 The button 1 and the transmission component 7 are connected to each other through a toothed engagement structure. The bottom of the button 1 has engagement teeth 11, and the bottom of the transmission component 7 has a toothed engagement portion 71. The positions of the engagement teeth 11 and the toothed engagement portion 71 are misaligned when the button 1 is not pressed. When the button 1 is pressed until the moving contact of the moving contact portion 6 abuts against the stationary contact on the pin, the transmission component 7 and the button 1 are tightly engaged through the toothed engagement structure. At this time, the position of the moving contact portion 6 is also limited, ensuring that the moving contact and the stationary contact of the moving contact portion 6 maintain a continuous conductive contact state.

[0025] To prevent the pin from shifting, the base 3 has a pin limiting part 33 at the pin fixing position. The width of the pin limiting part 33 in the vertical direction is slightly larger than the thickness of the pin. When the pin is placed in the pin limiting part 33, the horizontal position of the pin is also limited by the pin limiting part 33.

[0026] The movable contact portion 6 has two positions under the control of the button 1. The first position is when the button 1 is not pressed, at which point there is a gap between the moving contact and the stationary contact. The second position is when the button 1 is pressed until the moving contact and the stationary contact are in contact. When the button 1 is pressed, the button 1 drives the transmission member 7 to move downwards. The transmission member 7 then drives the movable contact portion 6 downwards until the moving contacts on both sides of the movable contact portion 6 contact the stationary contacts on the pins. At this time, the first moving contact 61 contacts the first stationary contact 41, and the second moving contact 62 contacts the second stationary contact 51. When this invention is installed in a circuit, the first pin 4 and the second pin 5 are each connected to one end of the circuit. Under normal conditions, there is no electrical connection between the first pin 4 and the second pin 5, and the circuit cannot be connected when the switch is pressed, remaining in an open circuit state. When button 1 is pressed, causing the moving contact 6 to contact the pin, the two stationary contacts form an electrical connection through the moving contact and the conductive plate 63. At this time, the entire circuit is in a conductive state. In the specific application scenario of this utility model, this means that the lighting circuit of a flashlight is in a conductive working state. When the force of pressing button 1 is released, the second elastic reset member 9 and the first elastic reset member 8 spring back. The springback releases the connection between the moving contact and the stationary contact, and the moving contact 6, the transmission member 7, and the button 1 return to the first position under the reset action of the elastic deformation force.
