Well, I think that the Pertronics must not be just a switch off/on. I think
that as the leading edge of the magnetic field encounters whatever the
switching device is, they 'Open' just like points and when the trailing edge
of the field exits whatever the switching device is, they 'Close', just like
a set of points.
So, the dwell would still be a factor when retaining the rest of the stock,
point type ignition. I think.
