Solution Overview
Problem
Conventional conducting switch mechanisms often suffer from inaccurate conduction due to shaking during the sliding process of movable terminal sets and have complex structures that are cumbersome to manufacture, prone to errors, and require welding of multiple metal parts.
Innovation Solution
A conducting switch mechanism featuring a housing, operating stem, fixed terminal set, movable terminal module, fulcrum bar, and elastic member, where the movable terminal module is formed by integral stamping to maintain contact precision and structural strength, eliminating the need for separate welding of terminal pivot portions and body portions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the movable terminal set is formed by welding multiple metal parts, then the structural strength is improved, but the manufacturing complexity and error risk increase
Solution Approach 1:
The patent merges multiple metal parts (terminal pivot portions and body portions) into a single integrally stamped movable terminal set. This eliminates the welding process while maintaining structural strength, as the integral structure provides inherent rigidity and eliminates weak points at welded joints. The manufacturing complexity is reduced by removing welding steps and associated quality control requirements.
2Strength
If the movable terminal set is formed by welding multiple metal parts, then the structural strength is improved, but the manufacturing time and cost increase
Solution Approach 1:
By combining multiple parts into a single integrally stamped component, the patent eliminates sequential welding operations and allows for high-speed stamping manufacturing. This significantly improves production efficiency and reduces manufacturing costs while maintaining the required structural strength through optimized integral design.
3Strength
If the movable terminal set uses a complex structure with multiple parts, then the structural strength is improved, but the contact precision decreases due to shaking during sliding
Solution Approach 1:
The integral stamping structure eliminates gaps and misalignments between multiple parts that cause shaking during sliding. The monolithic construction provides inherent rigidity and stability, ensuring consistent contact precision between the movable terminal set and fixed terminal set while maintaining structural strength.
Solution Approach 2:
The patent optimizes the geometric parameters of the integrally stamped movable terminal set, including the arrangement and dimensions of terminal pivot portions and body portions, to achieve both structural strength and contact precision in a single optimized structure.

AI summary
A conducting switch mechanism includes a housing, an operating stem is exposed from the housing, a fixed terminal set, a movable terminal module, a fulcrum bar, and an elastic member. The fixed terminal set is fixed on a base of the housing, and includes a pair of constant contact terminals, a pair of first pathway terminals, and a pair of second pathway terminals. The movable terminal module has a first movable terminal, a second movable terminal, and an insulating member. The insulating member partially clads the movable terminals. The structures of movable terminals are integrally stamped. One end of the movable terminals correspondingly abuts against the constant contact terminals, and another end of the movable terminals correspondingly contacts the first pathway terminal or the second pathway terminal. The elastic member is connected between the fulcrum bar and the movable terminal module.
