The winch manufacturers sell special contactor packages for this

battery if you try to raise and lower the anchor simultaneously. Such
a situation _is_ possible if you aren't careful how you wire up
individual contactors.




I use a center off on-off-on toggle switch, myself. You can't press up and
down simultaneously that way....

True - and safe if that one switch is the only control. However, on
many power boats, there will be winch controls at the lower helm and
on the flybridge, and foot switches on the foredeck - in that case, a
safety interlock against incorrect operation is required.
