Rocker Switch Illumination Layout for Precise Press Guidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing switching devices fail to precisely indicate the location of the control key for user input, especially in dark environments, as they typically illuminate the entire control key or specific areas only in one tilting position, lacking a method to alternately illuminate distinct zones to guide the user's finger.
Innovation Solution
The switching equipment features two light sources positioned under slots that alternate illumination based on the control key's angular position, ensuring that only one specific area is illuminated at a time, guiding the user's finger to the correct pressing location.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a permanent indicator light illuminates the entire control key, then the control key is visible in dark environments, but the precise location for user input is not clearly indicated
Solution Approach 1:
The patent divides the illumination function into two separate light sources: a first light source that illuminates the entire control key for general visibility, and a second light source that illuminates only a specific pressing area for precise input guidance. This segmentation allows each light source to fulfill a specific illumination purpose without interfering with the other.
Solution Approach 2:
The patent applies local quality by making different parts of the control key have different illumination characteristics. The first light source provides uniform illumination across the entire control key, while the second light source provides concentrated illumination only at the pressing area, creating distinct visual zones with different brightness levels to guide user interaction.
2Loss of information
If indicator lights are arranged on edges to form a luminous halo, then the control key position is indicated, but the precise pressing location is not clearly shown
Solution Approach 1:
The patent segments the indication function into two parts: the luminous halo formed by edge indicator lights that shows the control key position, and the second light source that specifically illuminates the pressing area. This segmentation ensures that position indication and pressing location indication are provided through separate, complementary mechanisms.
3Measurement precision
If a single light source illuminates the control key in only one tilting position, then the ON position is indicated, but the OFF position and precise pressing location are not clearly indicated
Solution Approach 1:
The patent merges the functions of two light sources into a single illumination system: the first light source provides general visibility by illuminating the entire control key, while the second light source provides precise position indication by illuminating only the pressing area. Both light sources work together to simultaneously achieve general visibility and precise position indication in dark conditions.
Solution Approach 2:
The patent employs periodic action through the tilting mechanism that alternates between ON and OFF positions. The second light source is activated only when the control key is in the ON position, creating a periodic illumination pattern that clearly indicates the active state while the first light source maintains continuous general visibility.

Function Achieved in This Case
This solution effectively alternately illuminates distinct zones on the device's facade, enhancing user experience by clearly indicating the precise location for pressing the control key, even in dark conditions, thereby improving operational accuracy and ease of use.

AI summary
The invention relates to a switching apparatus (1) comprising a control button (30) capable of pivoting about a pivot axis between two distinct angular positions relative to a flat portion (23) extending below the control button, and a lighting device comprising two light sources (112). According to the invention, said flat portion has two slots (24) arranged below the control button, opposite each other on a positioning axis perpendicular to said pivot axis, and the two light sources are placed below the flat portion to emit a luminous flux through the slots to the outside of said switching apparatus. The relative position of the slots and the control button is adjusted so that, in each of the two angular positions, the control button closes one slot and leaves the other slot free.
