Rocker Switch Illumination via Segmented Wedge Locks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rocker switch assemblies face difficulties in incorporating illumination mechanisms on both ends of the rocker switch actuator, particularly in locking configurations, which limits their versatility and functionality.
Innovation Solution
The implementation of pivotable wedge locks with a biasing member, such as a compression spring, allows the rocker switch actuator to be locked in multiple configurations while enabling space for lighting on both ends, using 'short' or 'long' wedge locks to accommodate various locking positions and configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a locking mechanism is implemented in a rocker switch assembly, then the switch can be locked in specific positions to prevent accidental switching, but it becomes difficult to provide illumination mechanisms on both ends of the rocker actuator
Solution Approach 1:
The locking mechanism is segmented into multiple independent wedge locks (first wedge lock and second wedge lock) that can operate independently on different sides of the rocker actuator. This segmentation allows each wedge lock to be positioned separately, creating clear zones that can accommodate illumination mechanisms on both ends of the actuator without interference from the locking components.
Solution Approach 2:
Different regions of the switch assembly are assigned different functions: the wedge locks are positioned in specific areas to provide locking capability, while the ends of the rocker actuator are designated for illumination mechanisms. This local differentiation of function allows the locking mechanism and illumination features to coexist without compromising either reliability or versatility.
2Reliability
If wedge locks are used to lock the rocker actuator in multiple positions, then secure locking is achieved, but the structural complexity of the assembly increases
Solution Approach 1:
The wedge locks are integrated with the existing rocker switch structure, utilizing the housing and actuator as part of the locking mechanism. The wedge locks engage with features already present in the switch assembly, such as the sides of the rocker actuator and the housing, thereby achieving secure multi-position locking without adding significant structural complexity or requiring entirely separate locking components.
Solution Approach 2:
The wedge locks are designed to automatically engage and disengage based on the position of the rocker actuator. As the actuator moves between positions, the wedge locks self-engage with the housing features to provide locking, eliminating the need for additional actuators, springs, or complex control mechanisms that would increase device complexity.

AI summary
A rocker switch assembly includes a housing having at least one bracket with a bracket stop formed therein, and a rocker actuator pivotably mounted on the housing. At least one wedge lock is pivotably mounted on the rocker actuator, the wedge lock pivotable between a locked position in which the wedge lock engages the bracket stop formed in the bracket, thereby preventing pivoting of the rocker actuator with respect to the housing in at least one direction, and a retracted position in which the wedge lock is disengaged from the bracket stop formed in the bracket so as to allow for pivoting of the rocker actuator with respect to the housing. A lock release button is also provided, actuation of which from a resting position to a release position causes the wedge lock to move to the retracted position.
