Bill,
When the switch failed on my 63 4, I just went down to my FLAPS and
picked up a mechanical switch and attached it to the frame that holds
the master cyl. Added a wire harness around the front, over the radiator
to hook up with the ends of the old switch. I believe Triumph did this
for the 4a and on as my 6 has a similar setup from stock. I am sure you
can rig up something similar for your 3.
