Description

Technical Field

[0001] The present application relates to the technical field of switches, and particularly to a double rocker LED power-on indicating switch. Background Art

[0002] An indicator light for indicating its power-on state is usually provided inside a rocker switch. Among them, LED lights are widely used because of their small size, high brightness, and long service life.

[0003] Chinese Utility Model Patent CN216120033U discloses a small-sized boat-shaped switch with a light. In this solution, the surface mount LED is disposed on the upper surface of a double-sided PCB. Mounting grooves are provided on two opposite side walls of the rocker. The double-sided PCB is inserted into the mounting grooves. In this solution, since it is necessary to open slots on the side walls of the rocker, the rocker needs to adopt relatively thick side walls, which increases the material cost on the one hand; on the other hand, the double-sided PCB is only fixed through the mounting grooves, and the firmness is not high. Summary of the Utility Model

[0004] In view of this, the present utility model provides a double rocker LED power-on indicating switch to solve the problems in the prior art that the double-sided PCB is fixed by means of slotting on the side walls, resulting in high material cost and poor firmness of the double-sided PCB.

[0005] The double rocker LED power-on indicating switch provided by the present utility model includes a base and a rocker button rotatably arranged with the base. The base has two groups of live wire pins, a middle pin, and a neutral wire pin. One end of the live wire pin extending into the base is provided with a static contact. A rocker contact piece is also provided in the base. A moving contact for contacting or disconnecting with the static contact is provided on the rocker contact piece. The rocker button includes:

[0006] An upper cover for transmitting LED light;

[0007] A support frame, including a bottom plate and side plates arranged on both sides of the bottom plate. A groove is provided in the middle of the top surface of the bottom plate. Both ends of the groove penetrate through the two side plates. U-shaped covers are respectively provided on the inner walls of the side plates. The U-shaped covers are buckled on the groove;

[0008] A PCB board, inserted and arranged in the groove.

[0009] For the above double rocker LED power-on indicating switch, the mounting groove of the PCB board is perpendicular to the two side plates of the support frame. Thus, the thickness of the side plates of the support frame can be reduced, and materials can be saved. In addition, U-shaped covers are respectively provided on the inner walls of the side plates. The U-shaped covers are buckled on the groove to limit and fix both ends of the PCB board. Therefore, the fixing firmness of the PCB board is improved.

[0010] In the above technical solution, preferably, two cylinders are respectively provided on the bottom surface of the bottom plate. The two cylinders are arranged side by side and are respectively provided with through holes, and the through holes respectively penetrate through the bottom of the groove.

[0011] In the above technical solution, preferably, the upper cover is made of a translucent material.

[0012] In the above technical solution, preferably, the cylinders are connected by rib plates.

[0013] In the above technical solution, preferably, rotating shafts are respectively provided on two side surfaces of the upper cover for rotatably connecting with the side walls of the base to form a rocker button structure.

[0014] As can be seen from the above technical solution, the double-rocker LED power-on indication switch provided by the present utility model solves the problems of high material cost and poor firmness of the double-sided PCB board in the prior art by using the side wall grooving method to fix the double-sided PCB board. Compared with the prior art, the present utility model has the following beneficial effects:

[0015] The installation groove of the PCB board is arranged perpendicular to the two side plates of the support frame. Thus, the thickness of the side plates of the support frame can be reduced, saving materials. In addition, U-shaped covers are respectively provided on the inner walls of the side plates, and the U-shaped covers are buckled on the grooves to limit and fix both ends of the PCB board. Therefore, the fixing firmness of the PCB board is improved. BRIEF DESCRIPTION OF THE DRAWINGS
