I'd be very careful about this. You certainly don't want to put them in
series, and simply putting them in parallel could damage one or the other,
or result in spurious operation.
I once characterized the switching requirements, but can't find the
results. I seem to recall the switch requires only a milliamp or so of
switching current. If so, you could probably safely fire the two in
parallel by putting a 1k ohm resistor in series with the center contact of
each winder, putting the other end of the resistors together, and switching
that against the outer contacts, which are wired together. The resistor
will isolate the Winders from each other.
Of course, a double-pole switch is the best way to isolate them -- perhaps
a double pole relay fired from a single pole switch, if your application
has a single output, such as a light beam trigger or mercury switch.
