I don't see a Bitcoin cash orange switch in the BTU Cash specific client.
the switch is on this website
https://blockchair.com/ front page (it shows you the block height) if you are running the BUCash clients you need to check your block high, it should be the same as the website. it may be your are not fully synced and as a result your transaction is not visible. (i think you may meed to mouse over one of the icons in the bottom right of the app to see your block height)
Is there a way to do this? How do I ensure I just don't reload the regular Bitcoin chain?
it can take a day or 3 to download the entire chain, I don't think you need to worry about loading the BTC chain, it will switch chains at the triggered block height.
I haven't had much luck finding an easy tool to manage my BCC. if you are not in a rush just wait until a good quality wallet from a reputable provider comes with the ability to sweep a private key. (
https://coinomi.com/ has the functionality but it does not support the older private key format that I use.)
I have been using
http://www.electroncash.org/ it allows me to import a private key and then broadcast a transaction to my storage addresses.
