Lathe Safety Chuck key Holder Lock out

This is a preview video of a new safety feature for a lathe.
It is a key Interlock system. That will not allow you to turn the lathe on or have the lathe running. Without the key, return to a specific pedestal. Or microswitch.
I have had this idea for around 15 years and never implemented it yet.
The reason for the preview video? Is I am looking for feedback. Because we have approximately one hundred lathes. That we need the tool with this safety feature. I would like to get it perfected. So, there is not. Twenty models with version 1 and 20 models with version 2.
Any feedback that you can provide? Insights on something I did not realize or see. I would appreciate it.
