<DIV><FONT size=2>I got fed up with OD auto-engaging as I changed from 2nd to
3rd so built a circuit that once out of an OD gear, it locked it out
semi-permanently until I turned the manual switch off and back on again.
That has a warning light to say it has been locked out, rather than one to say
it is engaged. More info here <A

<DIV><FONT size=2>That uses a relay which has been completely reliable, for a
time someone was selling a module based on a thyristor but a pal has one
and it keeps triggering when some other electrical circuit is switched off or
on. That also has a panel with a push-button for on, another for off, and
an LED but that needs mounting somewhere, mine just uses the standard
switch. A link to a circuit for that is there as well.</FONT></DIV>

would even work...</DIV></BLOCKQUOTE></BODY></HTML>
