A Good analysis why the original Healey switch and replacements do not =
work well. May choose to keep the original in a box and buy a Hella, or =
continue to do with out a switch and use a direct ground to the frame.

switch such as that made by Hella and others, sold on the Pegasus site.

My experience with the original Lucas Master switches has been a little =
different.=20
Many years ago, after having a newly installed NOS switch fail on my own =
car, I discovered that it had failed because the ground cable running =
from the switch to the frame was not properly installed.=20
The full starter current must pass through the switch then through the =
cable to ground. When there is resistance in that cable current passes =
through THE SPRING to then ground through the body of the switch and the =
switch mounting bracket.
This high current rapidly overheats the spring and it looses tension =
ruining the switch.
I have disassembled several of these switches to stretch the spring as =
suggested but often found that the brass of the spring had been totally =
annealed as a result of being overheated because of the current that had =
passed through them.
For my own car (and several others since) I made a new spring from =
copper coated steel welding wire wich lasted until I sold the car many =
years later.=20

Good to know you have the rivets.

The number one fault with both the original and the new switch is the =
spring inside looses its tension and you then loose the ground =

I have also had to take apart the new switches to make them work =
