It sounds like the switch has intermittent issues,
Have you tried using a foot pedal to control the on off function.
Just a suggestion to try.
I have never had this issue, But I use a foot pedal to control the on/off function, Not the arm switch

The on/off switch can collect dust over time and fail and you said that it's the original if I'm reading your post right. I had to replace one a few years back. There's a video on testing the switch and replacing it. https://www.youtube.com/watch?v=QihaA3zx5Ks. Good luck!
