There is a very serious difference between the two types
of selector magnets ... the Holding type actually has a cam
on the main shaft that pushes the armature against the sel.
magnet core, this avoiding the need for the magnetism from
the loop current to do all that work of moving the armature;
the PULLING magnet needs a lot of magnetic power to pull
that armature from resting [space] up against the magnet
core [mark]... so clearly the Holding magnet is preferable !!
But you don't really have a choice on any one machine,
because without that cam on the main shaft you don't
have the push for the holding magnet.
