My component level electronics is rusty, including RC circuit calculations, having been doing module swapping for years. This is probably a very simple question for the folks here....

Is this a reasonable circuit for a delay timer?

If so, how would I calculate the values of R &C for this...

1. Switch closes
2. After 5 seconds, the relay energizes and remains energized until switch is opened.

Thanks in advance!

What is the minimum activation voltage of the relay coil? What is the
maximum coil voltage of the relay? What is the typical resistance of the
relay coil?

I'm using the relay shown in this MK111 circuit...
