Interchangeable Control Mechanism for Low-Voltage Switches
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional low-voltage switches face challenges in interchangeability of control components, requiring complex maintenance procedures and high manufacturing and operating costs due to rigid functional designs and difficult access to connecting means, limiting their adaptability to varying application conditions.
Innovation Solution
A low-voltage switch design featuring removable connection means between the control mechanism and the mobile element, supported by a structural part via a hinge connection, allowing for easy replacement and interchangeability of control components without disassembling the entire switch, using first, second, and third removable connection means for simplified operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If conventional switches use fixed control mechanisms with complex connecting means, then structural stability is maintained, but maintenance difficulty increases and interchangeability is reduced
Solution Approach 1:
The control mechanism is segmented into modular components that can be independently removed and replaced. The connecting means are designed as separate removable elements rather than integrated fixed structures, allowing maintenance personnel to access and replace individual control components without disassembling the entire switch apparatus.
Solution Approach 2:
The control mechanism is extracted as a removable module from the main switch structure. The connecting means are designed to be separable, allowing the control mechanism to be completely removed and replaced with different control types (direct or storage) without affecting the core switch structure.
2Adaptability or versatility
If switches are designed with rigid functional configurations, then manufacturing simplicity is maintained, but adaptability to different applications is reduced
Solution Approach 1:
The switch structure is designed with universal mounting provisions that can accommodate different types of control mechanisms (direct control or storage control). The connecting means are standardized to work with various control configurations, allowing a single basic switch structure to serve multiple application requirements without requiring different manufacturing processes.
Solution Approach 2:
The control mechanism configuration is made dynamically changeable rather than fixed. The removable connecting means allow the control type to be adjusted based on application requirements, enabling the switch to adapt between different operational modes (direct or storage control) while maintaining the same basic structure.
3Adaptability or versatility
If entire switch apparatus is replaced to change control type, then functional requirements are met, but operating costs increase
Solution Approach 1:
The control mechanism is segmented as a separate replaceable module, allowing only the control portion to be replaced rather than the entire switch apparatus. This segmentation enables maintenance personnel to perform quick swaps of control mechanisms without disturbing the main switch structure, contacts, or mounting infrastructure.
Solution Approach 2:
The control mechanism is extracted as an independent replaceable component. The connecting means are designed to facilitate complete removal of the control mechanism from the switch structure, enabling rapid interchange between different control types (direct or storage) without requiring replacement of the entire switch apparatus or complex reassembly procedures.

AI summary
The present invention relates to a single-pole or multi-pole switch to be used preferably in Iow-voltage systems. The switch (1) comprises an outer casing (2) containing for each pole at least one fixed contact (10) and one mobile contact (20) which can be reciprocally coupled to/uncoupled from each other. The mobile contacts (20) are housed in suitable seats (25) provided on a mobile element (50). The switch (1) according to the invention is provided with a control mechanism (60, 61) comprising mechanical means supported by a structural part (70). This control mechanism (60, 61) is connected to the mobile element (50) through first removable connection means (64) and to the outer casing (2) through second removable connection means (65). The switch (1) also comprises means to support the mobile element (50) which are connected to the structural part (70) of the control mechanism (60, 61) through third removable connection means (66).
