I had a similar 2 switch set up, but added a third battery switch not in parallel to engine battery, in case the duff battery draws down the good ones. Third switch connects service batteries to engine circuit ahead of engine battery switch. As in normal use, third switch does not have a key inserted. Keys to engine and service batteries are on strings, to prevent loss, with engine key string long enough to reach third switch, but engine switch must then be off to remove key in order to switch on third emergencyswitch, hence no chance of cross connection. Service switch key not long enough to reach third switch, so can't inadvertantly connect service to dead engine battery in normal or abnormal use.
Normal operation switch on engine & service switches, and forget
