Dear Lew,
I will have to agree with Tom Metcalf concerning the use of a ROTAX PLC
switch in the MMM cars. The factory photos show that basically the ROTAX
PLC switch was used. In my opinion, so few original ROTAX PLC switches
survived because the "spade key setup" offered very little security &
the ignition portion of the switch was so-so even when new. It would
fail easily. The LUCAS PLC offered a regular key & better internal
parts. So it would have been easy to update to a better PLC switch early
on.
