Description

Technical Field

[0001] This utility model relates to the field of indicator button technology, and in particular to a split double-frame indicator button. Background Technology

[0002] An indicator button is a button with an indicator function, usually used on devices or interfaces to provide operation instructions or status feedback. Indicator buttons may have different designs and functions. The buttons usually have clear markings, such as text, symbols or colors, to indicate their function and purpose. When the button is pressed, it triggers an internal switch or sensor, thereby sending a signal to the device to perform the corresponding operation or change the state.

[0003] For example, Chinese Patent No. CN201430580Y discloses a low-height multi-directional indicator key structure, including a magnetic component, a keycap, and an elastomer. At least a portion of the magnetic component is installed inside the keycap, and the outer center of the elastomer is positioned adjacent to the keycap. The movement of the keycap and the magnetic component is restricted by the elastomer. The key feature is that the elastomer is a spiral structure that gradually expands outward from the central region of the elastomer. The outer edge of the spiral spring structure of the elastomer has a frame, which cooperates with the spiral spring structure.

[0004] Although the above technical solutions have solved the corresponding technical problems, they still have the following drawbacks:

[0005] The indicator buttons in the above technical solution are integrated into one structure, with the buttons and indicator lights combined.
