I'm with you, I would not think to use the switch in this way either but
that is how the diagram he was using did it. Fuse S6 is a 15 amp so the
current through the switch should be low enough that a properly rated
switch would be ok. Usually we think of relays as devices for use to
avoid putting the current load through the control switch but that is
not always how they are used.
