Abstract
Description
Technical Field
[0001] This application relates to the technical field of switches, and in particular to an electric light source switch. Background Art
[0002] Currently, electric light source switches are devices used to control the on / off state of circuits, turning electric light sources (such as light bulbs) on or off. There are various types of electric light source switches, each with its specific application scenarios and advantages.
[0003] Among related technologies, there exists a normally closed light source switch for a car armrest box. When the armrest box lid is closed, the internal light source is usually off; however, when the armrest box lid is opened, the internal light source automatically illuminates. This design provides a more convenient and safer user experience for drivers and passengers, especially at night or in low-light conditions, allowing them to quickly locate items stored in the armrest box.
[0004] The aforementioned electric light source switch mainly includes a switch base, a button movably mounted on the switch base, and a moving contact on the button. The switch base also contains a stationary contact opposite the moving contact, and a reset element for pushing the button back to its original position. When the button is subjected to external force, it separates the moving and stationary contacts, thus disconnecting the external electric light source circuit. When the external force is removed, the reset element pushes the button back into contact with the stationary contact, thus connecting the external electric light source circuit. However, some buttons are prone to wobbling and deviation in their sliding path during sliding, which reduces the stability and timeliness of triggering to some extent. Therefore, the structure needs improvement. Utility Model Content

[0008] Preferably, the limiting member is provided with a relief groove, the relief groove is provided with a plug-in post, and the moving contact piece is provided on the plug-in post.
[0009] Preferably, the plug post is provided with a connector, and the movable contact has a through-hole with a shape adapted to the connector, and the movable contact is limited on the connector through the through-hole.
[0010] Preferably, the housing is provided with a stationary contact piece, one end of which extends outside the housing, and the other end of which is provided with a contact element.

[0013] In summary, this application includes at least one of the following beneficial technical effects:
[0014] With the cooperation of the limiting component and the sliding groove, the stability of the button during sliding can be greatly improved. In addition, under the guidance of the surrounding limiting strip, the limiting component can ensure that the moving contact and the stationary contact separate or fit together in time, ensuring the timeliness of circuit switching.
[0015] By limiting one end of the reset spring within the receiving groove and sleeved the other end on the outside of the connector, unnecessary elastic deformation of the reset spring can be reduced, improving the stability of the reset spring during extension and retraction, ensuring that the reset spring extends and retracts along the sliding direction of the button, and guaranteeing the timely reset of the button.

Detailed Implementation
[0021] The present application will be further described in detail below with reference to the accompanying drawings.
[0022] This application discloses an electric light source switch.
[0023] Reference Figure 1 , Figure 2 as well as Figure 3 The electric light source switch includes an insulating housing 1, on which a button 2 is movably mounted. One end of the button 2 extends outside the housing 1, and the other end of the button 2 is fixedly mounted with a limiting member 3 that limits movement within the housing 1. Limiting strips 10 are integrally formed on a set of opposite inner sidewalls of the housing 1, with the length of the limiting strips 10 extending along the triggering direction of the button 2. The limiting strips 10 located on the same side of the inner wall of the housing 1 are symmetrically arranged on the left and right sides of the limiting member 3. A sliding groove 11 is formed between two adjacent limiting strips 10 and the inner sidewall of the housing 1 for the limiting member 3 to slide within the housing 1.
[0024] like Figure 2 , Figure 3 As shown, the limiting strip 10 and the outer wall of the limiting member 3 are in contact with each other. Under the limitation of the surrounding limiting strip 10, the limiting member 3 is slidably disposed in the housing 1 along the extension direction of the sliding groove 11. The top of the housing 1 has a through hole 100 for the button 2 to extend out of the housing 1. The width of the limiting member 3 is greater than the width of the through hole 100, so the limiting member 3 cannot pass through the through hole 100 to the outside of the housing 1, and the limiting member 3 is limited in the housing 1.
[0025] like Figure 2 , Figure 4 As shown, the bottom of the limiting member 3 is provided with a clearance groove 30, and an insertion post 31 is integrally formed in the clearance groove 30. The end of the insertion post 31 away from the button 2 extends out of the limiting member 3. A connector 32 is integrally formed on the insertion post 31 extending out of the limiting member 3, and a movable contact 4 located inside the housing 1 is installed on the connector 32. The movable contact 4 has a through-hole 40 whose shape matches that of the connector 32, and the movable contact 4 is limited on the connector 32 through the through-hole 40. The connector 32 is roughly polygonal in shape, which can limit the rotation of the movable contact 4 on the connector 32, ensuring the stability and accuracy of the movable contact 4 when triggered.
[0026] like Figure 2 , Figure 4As shown, a base 6 is inserted and fixed to the bottom of the outer casing 1. The base 6 has a receiving groove 60 facing the connector 32, and a return spring 7 located inside the outer casing 1 is installed on the base 6. The lower end of the return spring 7 is inserted and limited within the receiving groove 60, and the upper end of the return spring 7 is sleeved on the outside of the connector 32. The return spring 7 extends and retracts along the sliding direction of the button 2, and the return spring 7 is used to push the button 2 out of the through hole 100 to the outside of the outer casing 1, so as to reset the button 2.
[0027] like Figure 3 , Figure 4 As shown, a set of mutually opposing outer side walls of the base 6 are provided with retraction grooves 61, which are symmetrically arranged on both sides of the receiving groove 60. The retraction grooves 61 penetrate the inner and outer shell 1, and stationary contact pieces 5 are installed in the retraction grooves 61. The stationary contact pieces 5 are respectively inserted into and limited in their respective opposite retraction grooves 61. One end of the stationary contact piece 5 is located inside the shell 1, and the other end of the stationary contact piece 5 extends to the outside of the shell 1 through the retraction groove 61. The end of the stationary contact piece 5 is bent towards the limiting member 3 to form a contact member 50 located inside the shell 1. The contact member 50 is located on the sliding path of the moving contact piece 4 when it is reset. The two contact members 50 will abut against the moving contact piece 4 in the reset state. At this time, the external circuit will remain in a conductive state.
[0028] The implementation principle is as follows: With the cooperation of the limiting member 3 and the sliding groove 11, the stability of button 2 during sliding is greatly improved. Furthermore, guided by the surrounding limiting strip 10, the limiting member 3 ensures that the moving contact 4 separates from or engages with the stationary contact 5 in a timely manner, guaranteeing the timely switching of the circuit. In addition, by limiting one end of the return spring 7 within the receiving groove 60 and the other end sleeved outside the connector 32, unnecessary elastic deformation of the return spring 7 is reduced, improving the stability of the return spring 7 during extension and retraction, ensuring that the return spring 7 extends and retracts along the sliding direction of button 2, and guaranteeing the timely reset of button 2.
[0029] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
