[0006] The drawbacks of the above technical solution are: placing the resistor on the PCB board increases the cost; and special spring positioning equipment is required during assembly, making the assembly process cumbersome.

[0007] Therefore, how to provide an indicator light switch that is easy to automate and has a low cost has become a problem that the industry needs to solve. Utility Model Content

[0008] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an indicator light switch that is low in cost and can be automatically assembled.

[0009] To achieve the above objectives, this utility model provides an indicator light switch, which includes:

[0010] Base;

[0011] The power-on mechanism includes a button and a power-on terminal that can contact or separate from the base. A ratchet and a power-on spring are provided between the button and the power-on terminal. A PCB board is provided at the bottom of the button, and an indicator light is provided on the PCB board.

[0012] The conductive mechanism includes several resistors and several conductive springs. The resistors are fixed on the base. The top of the conductive springs contacts the PCB board, and the bottom of the conductive springs contacts the base or the resistors.

[0013] The base has conductive areas for placing various components.

[0014] The buttons are transparent to allow the indicator lights to shine through.

[0015] The indicator light will illuminate when the indicator light switch is powered on; it will turn off when the power is off.

[0016] In this invention, the energized spring is connected to the base via a movable connecting plate; the bottom end of the connecting plate is fixed to the base, and the top end of the connecting plate is fixed to the energized spring; when the energized spring extends or retracts, it drives the top end of the connecting plate to move.

[0017] In this invention, the button is located above the power-on terminal.

[0018] In this invention, the base is provided with power contacts that can contact the power terminals.

[0019] In this invention, the base is provided with a resistor groove for placing a resistor, and the resistor is fixed in the resistor groove; the resistor can reduce the current, and it is in series with a conductive spring.

[0020] In this invention, the indicator light switch further includes a detachable housing, which is connected to the base and encloses a cavity.

[0021] In this invention, the outer shell is provided with several through holes that correspond one-to-one with the conductive springs, and the conductive springs pass through the through holes.

[0022] In this invention, the button is located on the top of the outer shell; the outer shell is provided with several limiting posts, which can control the movement of the button in the direction of extension and retraction of the energized spring.

[0023] In this invention, the energized spring is located between the ratchet and the energized terminal; the ratchet is rotatably mounted on the top of the energized spring, and the energized terminal is fixed to the bottom of the energized spring.

[0024] In this invention, the ratchet is located below the PCB board and passes through the outer casing.

[0025] In this solution, pressing down the button pushes the ratchet downwards and compresses the energized spring, thereby achieving contact or separation between the energized terminal and the energized contact.

[0026] During the assembly of the aforementioned indicator light switch, since the PCB board assembly is in direct contact with the conductive spring, there is no need to use a post inserted into the inner diameter of the conductive spring for positioning, making the structure reasonable and easy to assemble; at the same time, the resistor is not placed on the PCB board, which can reduce costs.

[0027] After the other parts are assembled, the penultimate step is to insert the conductive spring into the through hole, and the final step is to install the button. At this point, the PCB board is in contact with the conductive spring, and the assembly is complete.

[0028] The movement of the energized mechanism in this invention is achieved by using buttons, ratchet, and springs. This is a publicly disclosed technical solution, similar to the movement of a pen refill when pressed in daily life (see Chinese patent application 201821579827.2). Therefore, the specific details will not be elaborated further.

[0029] This invention solves the technical problems of high cost and complicated assembly of general switches, while reducing costs and enabling automated assembly.

[0030] The present invention will now be described in further detail with reference to the accompanying drawings. Attached Figure Description
