Reversible Retaining Element for Electrical Switch Mode Configuration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical switches with breakable retaining elements face issues in reversible operation, leading to loss of additional parts and instability in switching modes, as they cannot easily revert to stable two-position operation once the retaining element is removed.
Innovation Solution
A reversibly movable retaining element that transitions between a retaining position to maintain the compressible element in its inactive state and a separated position, allowing users to configure the switch between push-button and reciprocating modes without additional parts, ensuring the element is integral with the base to prevent loss.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a breakable retaining element is used to release the compressible element for push-button operation, then push-button operation is achieved, but the retaining element cannot be replaced and the switch cannot revert to stable two-position operation
Solution Approach 1:
The retaining element is designed to be movable between a retaining position (maintaining the compressible element in its inactive state) and a released position (allowing the compressible element to extend and constrain the trainer). This dynamic design enables the switch to be reconfigured between push-button mode and stable two-position mode, resolving the contradiction by making the system adaptable while maintaining reliability in both states.
Solution Approach 2:
The retaining element serves multiple functions: it can maintain the compressible element in the inactive state for stable two-position operation, and it can be moved to release the compressible element for push-button operation. This multi-functionality allows a single component to support both operating modes, eliminating the need for additional parts and enabling reversible configuration.
2Adaptability or versatility
If a removable retaining element is used to achieve reversible operation, then the compressible element can be released, but an additional part is required and there is a risk of loss of the removable element
Solution Approach 1:
The retaining element is integrated with the base structure, forming a single unified component. This merging eliminates the need for separate removable retaining elements while preserving the ability to release the compressible element. The retaining element is movably connected to the base, allowing it to be positioned in retaining or released states without requiring additional parts, thus reducing device complexity while maintaining reversible operation.
3Ease of manufacture
If the retaining element is integral with the base, then production is simplified and part loss is avoided, but the compressible element cannot be released for push-button operation
Solution Approach 1:
The retaining element is designed as a movable component integrated with the base, capable of transitioning between a retaining position (where it maintains the compressible element in its inactive state) and a released position (where it allows the compressible element to extend). This dynamic design enables push-button configuration while maintaining the benefits of an integral structure, simplifying production and preventing part loss while preserving adaptability.

AI summary
The invention relates to an electrical switch comprising a base and a driver (126) mounted to pivot within the base (110) between two stable positions to bring a movable contact element into or out of contact with a fixed contact element. A compressible element (150) is adapted to be inactive with respect to the driver (126), to allow the driver to freely assume either of the two stable positions, and to be received between a bearing surface of the base and the driver (126) and constrained against the driver (126), to force the driver (126) into only one of the two stable positions.A retaining element (117, 119) made of material with the base and adapted to maintain the compressible element (150) in its inactive state with respect to the trainer (126) is reversibly movable between a retaining position where it maintains the compressible element (150) in its inactive state with respect to the trainer (126) and a disengaged position where it allows free extension of the compressible element (150) up to the trainer (126).
