FWIW, the same thing could be done by copying the switch arrangement
used on a TR4 which has the switch mounted on the front end of the
bracket holding the master cylinders. That button works the opposite of
what you describe, that is it is normally open. When the brakes are
used the button is pressed by the end of the pushrod.
Let me know if you want a close-up photo of the arrangement.
