Lockable Push Button Actuator Retrofit Kit for Electrical Switch Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lockable push button actuator mechanisms used in mechanical locking systems do not efficiently utilize the relative movement between the tubular rear component and the plunger to operate an electrical switch, limiting their conversion to electrically operated locking systems.
Innovation Solution
A kit and method that replace the nosecone shaped member with an adapter carrying an electrical switch, allowing the plunger to operate the switch when the keyway is turned to the vertical locked orientation, enabling the push button actuator mechanism to function as a component of an electrically operated locking system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a lockable push button actuator mechanism is used for mechanical locking systems, then the mechanism provides reliable mechanical locking functionality, but it cannot operate an electrical switch effectively
Solution Approach 1:
The actuator mechanism is modified to perform multiple functions: it maintains its original mechanical locking capability while simultaneously gaining the ability to operate an electrical switch. The plunger is designed to engage with both mechanical locking components and the electrical switch operator, allowing a single mechanism to control both mechanical and electrical locking systems.
Solution Approach 2:
The electrical switch is positioned within or adjacent to the actuator housing, with the switch operator arranged to be engaged by the plunger that already exists in the mechanical actuator. This nested arrangement allows the electrical components to be integrated into the existing mechanical structure without requiring a completely separate actuation mechanism.
2Adaptability or versatility
If the plunger is designed to engage the electrical switch operator, then the relative movement between the tubular rear component and plunger can operate the switch, but this requires modification of the existing actuator components
Solution Approach 1:
The retrofit kit divides the conversion process into separate, manageable components: an adapter assembly that interfaces with the existing tubular rear component, and an electrical switch with its operator. This segmentation allows each component to be manufactured independently and assembled during retrofitting, simplifying the conversion process.
Solution Approach 2:
An adapter component serves as an intermediary between the existing mechanical actuator components and the new electrical switch. The adapter facilitates the connection and ensures proper alignment and engagement between the plunger and the switch operator, making the retrofit process easier and more reliable.
3Ease of operation
If the push button is depressed to move the plunger rearwardly, then the electrical switch can be operated, but the tubular rear component must be disconnected from the push button for this to work
Solution Approach 1:
The actuator mechanism incorporates dynamic disconnection and reconnection features that allow the tubular rear component to be easily disconnected from the push button during retrofitting, and later reconnected when needed. This dynamic configuration enables the system to switch between different operational modes (mechanical only, electrical only, or both) as required.

AI summary
A simple kit of parts is provided that can be used to replace a few easily removed elements of a lockable push button actuator of a mechanical locking mechanism to convert the push button actuator to a lockable actuator for controlling a switch that can serve as a component of an electrical locking system. Other aspects of the invention relate to a method of making the mechanical to electrical conversion, and to a lockable actuator for operating an electrical switch connected to the actuator.
