Electrical Switch Arrangement with Transverse Spring Guide
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical switch arrangements with visual displays for indicating switching states are often bulky and noisy due to vertically aligned springs, which obstruct reliable state display and require more installation space.
Innovation Solution
A spring is positioned at right angles to the button's movement within the switch housing, guided in a two-dimensional heart-shaped curve or U-shaped track, reducing structural height and noise generation, with a resilient switching mat and translucent components for enhanced haptics and light distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the spring is aligned vertically in the switch housing, then the switch can achieve reliable switching states, but the structural height increases and installation space is consumed
Solution Approach 1:
The spring is reoriented from a vertical alignment (one-dimensional) to a transverse alignment perpendicular to the button's direction of motion. This dimensional change allows the spring to function effectively while reducing the structural height in the vertical direction, enabling compact installation in space-constrained environments without compromising switching reliability
2Reliability
If the spring is guided over ramps with sharp drops in a three-dimensional guide track, then the switching states can be achieved, but noise is generated when the spring passes over the ramps
Solution Approach 1:
The guide track is redesigned from a three-dimensional path with ramps and sharp drops to a two-dimensional heart-shaped curve. This planar configuration eliminates the need for the spring to traverse vertical ramps, thereby preventing the generation of noise while still enabling the spring to assume distinct positions that reliably indicate switching states
3Object-generated harmful factors
If the spring is guided in a two-dimensional heart-shaped curve, then noise generation is minimized and structural height is reduced, but the spring must be precisely positioned to ensure reliable switching
Solution Approach 1:
The guide track is designed as a heart-shaped curve with specific geometric characteristics. The curved path provides natural guidance for the spring, ensuring that the spring assumes well-defined positions at key points in the curve. This geometric design inherently guides the spring into the correct positions, reducing the need for high manufacturing precision while maintaining reliable switching state indication

Implementation Method 1
A spring (8) is arranged inside the button (5) approximately at right angles to the direction of movement of the button (5), wherein the spring (8) is guided in a guide track (13) in sections of the switch housing (1). The spring (8) has the form of a wire section that is curved into an approximate U-shape

AI summary
An electrical switch arrangement has a switch housing and a button guided in the switch housing. The button can be brought into two fixed switching states. A display indicates when at least one of the switching states is reached. A U-shaped spring is arranged inside the button approximately at right angles to the direction of movement the button. The spring is guided in a guide track formed in sections of the switch housing.
