Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a symmetrical fork-like head mechanism with compression spring is used, then reliable electrical contact switching is achieved, but production and assembly complexity increases
Solution Approach 1:
The patent combines the fork-like head and compression spring into an integrated rocking push-button assembly. The button itself incorporates the fork structure that directly engages the anchor, eliminating the need for separate fork and spring components. This merging reduces part count and simplifies assembly while maintaining the reliable contact switching function through the elastic deformation of the integrated button structure.
Solution Approach 2:
The rocking push-button serves multiple functions simultaneously: it acts as the actuating mechanism, the fork-like engagement structure, and the compression spring element. The button's elastic material properties provide the necessary mechanical compliance and force storage, making it a multi-functional component that replaces several separate parts in traditional designs.
2Reliability
If an intricate mechanism with multiple components is used, then electrical contact control is achieved, but manufacturing complexity increases
Solution Approach 1:
The patent merges multiple functional components into a single molded rocking push-button assembly. The fork structure, elastic element, and actuating button are formed as one integrated component through molding processes, significantly reducing the number of separate manufacturing steps and assembly operations required while ensuring reliable electrical contact control.
Solution Approach 2:
The patent utilizes the elastic properties of the button material as a key parameter, allowing the structure to provide compression and rebound forces without requiring a separate metal spring. This material parameter change enables the mechanism to be manufactured using plastic molding techniques rather than requiring precision metalworking and assembly of multiple mechanical components.

AI summary
The present invention refers to an electrical switching device comprising a rocking push-button which influences an electrical control of various switching devices, such as of selector switches, rocker switches, multiple-way switches, single-pole and double-pole switches, and similar. An elastic means (14) is inserted into a tubular extension (16) of a rocking push-button (3), which projects through a cover (2) into a body (1) of the electrical switching device up to the immediate vicinity of a switching element (11), which can be actuated by means of the rocking push-button (3) with said elastic means (14) and a toggle slider (15). The free end of the tubular extension (16) is formed with a snap-on blocking means (18) configured to receive and to movably cooperate with a counter-blocking means (19) formed on said toggle slider (15).
