Anchor Marine makes some that work like those at your house. West Marine carries them for about $17 each. Since I seem to have missed the link to the pic(s) I don't know what those in the Workz car look like to ID them.

Yes circuit breakers work great! They are the only way to go.. Here is a good source to get them: Electronic Supply 1-800-622-3726. At least thats the contact info I was givien a while back. I have just never needed such parts since then. Hope this helps.
