Clutch ignition switch

[fahmasan]

First of all a big THANK YOU to all on this forum. Saved me a ton of time and money.
Last week or so my 1997 Boxster (52386) original miles, would not start sometimes. I mean nada. So I came to the forum, and it was the ignition cut-out switch on the clutch.
Replaced it with new one, worked fine for a few days, and back to the original problem. Funny thing is, I took it off the clutch, and manually held it down, bingo starts everytime.
Any ideas? Could there be a piece missing off the clutch pedal. It is simply screwed to the clutch rod at the top where the cruise control switch is located.
Many thanks in advance for any advice!
