constant momentary need info

As always... allow for me not understanding something... but this is my confusion: ...in the original circuit, switched power goes to 86 on R1. So if 30 from R2 connects to 86 on R1, 30 is getting switched power. Contacts 30/87a on R2 are normally closed, so the grounded 87a on R2 is connected to R2-30 when the switch is thrown just before the relay energizes. So, the way I see it, switched power is connecting to ground for a split second when the switch is first thrown before R2 can pull the 30/87a contacts open. Am I still missing a key concept? Should I post what I have drawn to see if I've miss-connected something?

Yes post the picture.

Thanks.. got it figured out. I was leaving a line in place that you had removed. I'll post a diagram for future reference for anyone that wants to do the same once I draw it up a little more neatly. Thanks for all the help.
