Does anyone know of a 2 battery switch that just allows for the use of one

Thanks.
The usual 1-both-2-off can be used this way. If you don't like it,
don't use it (the both position) Some day you might want it. Some
day you might want to charge both batteries at once.

A physical barrier to the both position might suit you.

Regardless, 2 simple off on swithes still allow a both selection.
Heavy enough switches not of the usual configuration in use in
millions of boats might well cost more, and as such, do not offer
the field defeat swith protection feature found in the typical switch.
