Pivotable Cover Switching Device for Carrier Rail Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electrical switching devices require significant space for mounting and dismounting, and their securing devices can be difficult to access, especially in series connections, making them cumbersome and less user-friendly.
Innovation Solution
A switching device with a pivotable housing cover that acts as both a signal contact connector and an actuating element for the securing device, allowing for easy mounting and dismounting by simultaneously closing or opening the contact connection and locking or unlocking the device from the carrier rail.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional securing devices with fixed holding geometry are used, then the switching device can be reliably mounted on the carrier rail, but the device requires significant space for mounting and dismounting operations
Solution Approach 1:
The patent applies the dynamics principle by making the holding geometry movable rather than fixed. The holding geometry can shift between a mounting position (where the switching device can be placed on the carrier rail) and a locked position (where it secures the device firmly). This dynamic adjustment allows reliable mounting while reducing the space required for operations.
2Reliability
If conventional securing devices are used in series connections, then the switching devices can be mounted on the carrier rail, but the securing device or actuating element becomes difficult to access
Solution Approach 1:
The patent applies the multi-functionality principle by designing the cover to serve multiple purposes: it acts as both the actuating element for the holding geometry and as a protective cover for the switching device. By integrating these functions, the cover remains easily accessible for operation while the device maintains stable mounting when secured to the carrier rail.
3Ease of operation
If a manually operable actuating element is provided for the securing device, then the holding geometries can be locked or unlocked, but the device complexity increases
Solution Approach 1:
The patent applies the merging principle by combining the actuating element and the cover into a single integrated component. The cover itself serves as the actuating element that directly interacts with the holding geometry, eliminating the need for separate actuators or complex mechanisms. This integration maintains manual control capability while significantly reducing device complexity.

AI summary
A switching device having a housing, with a cover that can pivot about a rotational axis, and a securing device for carrier rail mounting. The cover has at least one coupling contact for an electrical and/or signal-type contact connection with at least one engageable switching device. A closing or releasing of the contact connection occurs with a pivoting of the cover. A locking or unlocking of the securing device occurs with a pivoting of the cover. The securing device has a spring-elastic clipping element shaped on the housing, for force-locking securing to a carrier rail end face, and has a sliding element, which is mounted such that it can slide in a linear manner within the housing and is coupled to the cover, for interlocking securing to the carrier rail end face opposite the clipping element.
