Switch Device Guide Structure for Narrow Space Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional switch devices lack a guide structure between the housing and the mounting member, making attachment complex, especially in narrow spaces.
Innovation Solution
The switch device features a housing with guide concave parts or protrusions that guide external terminals into the housing, along with a positioning structure to ensure precise alignment and attachment to an external base material, facilitating easy installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If no guide structure is provided between the housing and mounting member, then the switch device can be attached to mounting members with wide spaces, but attachment becomes complex when the mounting member has narrow spaces
Solution Approach 1:
The patent introduces guide concave parts and guide protrusions as intermediary structures between the housing and mounting member. These guide structures act as mediators that facilitate the insertion and alignment of external terminals into the housing, enabling easy attachment even in narrow spaces without requiring complex adjustment procedures
2Area of stationary object
If the mounting area is narrow, then space utilization is improved, but attachment work becomes complex without guide structures
Solution Approach 1:
The guide concave parts and guide protrusions are pre-formed on the housing before attachment. These preliminary guide structures prepare the housing in advance to receive external terminals, ensuring that even when mounted in narrow areas, the attachment process remains simple and straightforward without requiring complex on-site adjustments

AI summary
A first guide support (13) and a second guide support (14) are integrally formed on an external base material (10) to which external terminals (11a) are fixed. Guide protrusions (25) and guide concave parts (26), which extend vertically, are formed on the housing (20a) of a switch device (20). When each guide protrusion (25) and its corresponding guide concave part (26) are guided by a first guide support (13) and a second guide support (14) during the attachment of the switch device (20) to the external base material (10), the switch device (20) can be easily attached.
