More or less, like the one shown in this video:


But more modern modern models will do as well.

Thank you.

What counts here as "actuation force"?

There's the force required to make a typebar reach the platen, but then there's the force required to make a good, dark impression on the page. That's something that will vary depending on the condition of the ink ribbon.

I've found that the force required to make readable type on a page is significantly higher than that required to simply advance the platen by a keystroke.

On a mechanical typewriter you will have to press the keys at speed. It is not just about how much resistance there is.

As several people have noted it's more about force than speed here, but based off my Remington I'd say definitely several hundred cN.
