[0001] This utility model relates to a switch with a separate indicator light. Background Technology

[0002] Push-button switches are widely used in daily life to control the on / off state of circuits. Many switches have indicator lights to show their status, and the overall structure and position of the indicator lights vary between different switches. Therefore, finding a reasonably structured indicator light becomes a problem that needs to be solved.

[0005] Chinese Patent 202120019909.7 discloses a multi-position push-button switch, comprising: a first conductive sheet, a second conductive sheet, and two or more push-button switches; the push-button switches include: a switch housing, a conductive moving contact, a ratchet switch, and an indicator light circuit; the conductive moving contact is fixed inside the switch housing, the ratchet switch is fixed inside the switch housing, and the spring of the ratchet switch abuts against the elastic actuating part of the conductive moving contact; the first conductive sheet is fixed inside the switch housing of the two or more push-button switches, serving as a conductive stationary contact that cooperates with the conductive moving contact; the second conductive sheet is fixed inside the switch housing of the two or more push-button switches; the first power connector of the indicator light circuit is connected to the conductive moving contact, and the second power connector of the indicator light circuit is connected to the second conductive sheet.

[0006] The drawbacks of the above technical solution are: structural limitations and cumbersome assembly.

[0007] Therefore, how to provide a switch with high assembly precision and stable reliability has become a problem that the industry needs to solve. Utility Model Content

[0008] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a switch with a separate indicator light, which has high assembly precision and is stable and reliable.

[0009] To achieve the above objectives, this utility model provides a switch with a detachable indicator light, the switch comprising:

[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.

[0012] The conductive mechanism includes a PCB board and several conductive springs; the top of the conductive spring contacts the PCB board, and the bottom of the conductive spring contacts the base; several indicator lights are provided on the PCB board.

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

[0014] The indicator light will illuminate when the switch is powered on; it will turn off when the power is off.

[0015] 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.

[0016] In this invention, the button is located above the power-on terminal.

[0017] In this invention, the base is provided with power contacts that can contact the power terminals.

[0018] In this invention, a conductive block that contacts the conductive spring is provided on the base.

[0019] In this invention, the switch further includes a detachable housing, which is connected to the base and encloses a cavity.

[0020] 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.

[0021] In this invention, the button passes through the outer shell; the button can move in the direction of extension and retraction of the energized spring.

[0022] 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 fixedly connected to the bottom of the energized spring.

[0023] 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.

[0024] Traditional indicator lights are located below the button, with the light-transmitting point in the button area. To prevent the light from being blocked, the overall structure of the switch is restricted. In this invention, the indicator light is moved out and shines through a location other than the button, allowing for greater product design diversity.

[0025] The PCB board is in direct contact with the conductive spring and is fixed in place. When the button moves up and down to switch between ON and OFF, the PCB board does not move. The structural design is reasonable.

[0026] 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.

[0027] This invention solves the technical problems of high cost and complicated assembly of general switches, resulting in lower cost, automated assembly, and high production efficiency.

[0028] The present invention will now be described in further detail with reference to the accompanying drawings. Attached Figure Description
