Multifunction Switch With Swingable Control Pin For Electrical And Mechanical Actuation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional switches lack a switching function for both electrical and mechanical elements, leading to increased complexity and cost when attempting to incorporate both functionalities.
Innovation Solution
A multifunction switch design featuring a swingable control body with a control pin, a movable contact, and a movable element that allows for both electrical and mechanical switching through a single mechanism, utilizing a control pin to swing and press the movable contact against a fixed contact, while also swinging to operate mechanical elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional switch is designed to only perform electrical contact switching, then the structure remains simple and cost-effective, but it lacks the capability to perform mechanical element switching
Solution Approach 1:
The control pin is designed to perform dual functions: it acts as an electrical contact by pressing the movable contact against the fixed contact, and simultaneously serves as a mechanical actuator by swinging to operate the movable element. This multi-functionality allows a single component to replace what would traditionally require separate electrical and mechanical switching mechanisms, thereby increasing adaptability while maintaining structural simplicity
2Adaptability or versatility
If additional switching functions are added to the conventional switch, then the versatility increases, but the number of parts increases and costs increase
Solution Approach 1:
The invention merges the electrical contact function and the mechanical actuation function into a single integrated mechanism. The control pin that swings to control the switch also directly actuates both the electrical contact (by pressing the movable contact) and the mechanical element (by swinging through it). This consolidation reduces the number of separate parts needed, as the same moving component performs multiple functions that would traditionally require separate actuators
3Adaptability or versatility
If a multifunctional switch is created by adding more components, then the versatility improves, but the manufacturing cost increases
Solution Approach 1:
By designing the control pin to serve as both an electrical contact and a mechanical actuator, the invention eliminates the need for additional components that would increase manufacturing cost. The single control pin mechanism replaces what would traditionally require separate electrical contacts and mechanical actuators, reducing part count and assembly complexity, thereby improving ease of manufacture while maintaining the desired multifunctionality

AI summary
A multifunction switch has a switching function for an electrical contact switch and a switching function for a mechanical element. The multifunction switch includes a swingable control body having a control pin, a movable contact coming into contact with the control pin, and a movable element having the control pin running therethrough and supported so as to be swingable. With the control pin being swung, the movable contact is pressed by the control pin to come into contact with a fixed contact and the movable element is swung by the control pin to implement mechanical switching for an additional element.
