Description

Technical Field

[0001] The utility model relates to the field of dip switches, in particular to a dip switch for displaying signal states. Background Art

[0002] The DIP switch is also called a DIP switch or a toggle switch. It is an address switch used for operation and control, and uses the binary coding principle of 0 / 1. It is widely used in computer motherboard overclocking, wireless communication, radio and television equipment, FM coding, computer software programming of automation equipment, CNC equipment, instruments (wireless remote control, time relay, temperature controller, counter) and automation control, and control components in preset circuits.

[0003] Although the existing DIP switch can realize the function of adjusting the code, when there is a short circuit or poor contact inside the DIP switch, the signal sent by the switch will be wrong, affecting the normal use of the equipment. However, it is not possible to intuitively find out whether the DIP switch is faulty. It is necessary to use a multimeter or other measuring instrument to check the DIP switches one by one to find out whether the equipment abnormality is caused by the fault of the DIP switch. As a result, the maintenance time is increased, affecting the normal use of the equipment. Therefore, the utility model proposes a DIP switch that displays the signal status. Summary of the invention

DETAILED DESCRIPTION

[0020] The present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0021] In this embodiment, refer to Figure 1-Figure 5, a specific implementation of a dial switch for displaying a signal state includes a housing 1, a push button 2 installed in the housing 1, a guide piece 3 fixed on the push button 2, and a first pin 4 and a second pin 5 respectively fixed on both sides of the housing 1, and the housing 1 is installed with a plurality of lamp beads 6, and the lamp beads 6 are respectively connected and matched with the guide piece 3 and the second pin 5 through a first electrode sheet 7 and a second electrode sheet 8. The housing 1 is provided with a through hole corresponding to the lamp bead 6, so that the lamp bead 6 can emit the light source outward through the through hole. The housing 1 is provided with a mounting groove for accommodating the lamp bead 6, the first electrode sheet 7 and the second electrode sheet 8, and the lamp bead 6, the first electrode sheet 7 and the second electrode sheet 8 are fixed by an adhesive so that they are firmly installed in the mounting groove. The mounting groove is set in the spacing between the push buttons 2 to improve the space utilization. The design of the mounting groove makes the layout of each component more reasonable and improves the compactness and stability of the overall structure.

[0022] Furthermore, the housing 1 fixes the push button 2 through a sliding groove, and the width of the sliding groove fits the width of the push button 2, so that the sliding of the push button 2 is more stable and smooth. The guide piece 3 is fixed to the push button 2 through an adhesive or a latch, so that the guide piece 3 moves as the push button 2 slides.

[0023] like Figure 3-Figure 4 As shown, the working principle of the utility model is: by turning the push button 2, the control guide 3 is connected to the first electrode sheet 7, so that the current enters the lamp bead 6 through the first electrode sheet 7, so that the lamp bead 6 lights up and transmits the current to the second pin 5 through the second electrode sheet 8, thereby sending a signal. When the guide 3 is disconnected from the first electrode sheet 7, the current cannot be transmitted, so that the lamp bead 6 is extinguished, thereby disconnecting the signal. Therefore, the signal state of the dial switch can be observed by lighting or extinguishing the lamp bead 6. This allows the source of the fault to be discovered in time and repaired or replaced.

[0024] Furthermore, the housing 1 includes a combinable base 9 and an end cover 10. The base 9 and the end cover 10 are designed to be tightly matched, and their mutually matched sizes are tightly matched, so that they can be firmly fixed without screws or other materials. A sealing ring is provided on the lamp bead 6, and the sealing ring is firmly pressed by the cooperation of the end cover 10 and the base 9, and the lamp bead 6 is fixed for a second time.

[0025] Furthermore, the lamp bead 6 is provided with a positive spring piece 11 and a negative spring piece 12 respectively connected and matched with the first electrode sheet 7 and the second electrode sheet 8. The positive spring piece 11 and the negative spring piece are made of elastic metal, so that the first electrode sheet 7 and the second electrode sheet 8 do not need to be connected by welding or other methods, and the first electrode sheet 7 and the second electrode sheet 8 can be directly installed to fit. This makes the installation or replacement process more convenient and quick.

[0026] Furthermore, the housing 1 and the push button 2 are respectively provided with a positioning groove 13 and a positioning block 14 for cooperation with each other. A gap is left between the positioning groove 13 and the positioning block 14, and an arc design is adopted, so that the sliding of the push button 2 is smoother and the resistance is reduced. In addition, the cooperation between the positioning groove 13 and the positioning block 14 also ensures the stability of the push button 2 in the housing 1, preventing it from shaking or falling off during use.

[0027] Furthermore, a retaining edge 15 is provided in the housing 1. The retaining edge 15 can prevent the guide piece 3 from directly contacting the second pin 5, thereby causing a short circuit in the circuit and directly sending a signal without the lamp bead 6, resulting in an erroneous judgment and sending an erroneous signal, thereby affecting the control of the device.

[0028] Furthermore, a support block 16 is provided at the bottom of the push button 2. The support blocks 16 are respectively located on both sides of the push bottom and fit with both sides of the sliding groove, which not only improves the stability of the push button 2 in the sliding groove, but also plays a supporting role, thereby preventing the push button 2 from tilting excessively in the sliding direction when sliding, thereby deforming the guide piece 3 and affecting its use.

[0029] Furthermore, the housing 1 is provided with an indicator mark 17. Through the indicator mark 17, the corresponding position, working state and switch direction of each dial switch can be clearly understood, so as to avoid pushing the wrong push button 2 due to different installation directions or debugging positions, resulting in abnormal coding, affecting the control effect, and thus causing equipment failure or damage.

[0030] The beneficial effects of the utility model are as follows: a plurality of lamp beads 6 are installed through the housing 1, and the lamp beads 6 are connected and matched with the guide piece 3 and the second pin 5 through the first electrode piece 7 and the second electrode piece 8 respectively. The current needs to pass through the lamp beads 6 to reach the second pin 5. When the guide piece 3 is connected or disconnected with the first electrode piece 7, the lamp beads 6 also light up or go out accordingly. Thus, the signal state of the switch can be displayed through the lamp beads 6. The time spent on finding the source of the fault during maintenance is saved. Thus, the practicality and convenience of the dial switch are improved.
