Nicole killswitch

Since I installed a killswitch on my Dot, I've been using it happily and wondered how I could live without it for so long (I'm currently recording demos, there should be some samples to hear soon - I mean soon in my usual very slow pace...). But after a few thousands clicks, the push button started to be noisy, and I realized that the cheap piece or gear I acquired for less than 1€ wasn't designed for such an intensive use.

So I ordered a Rolls Royce killswitch from French Luthier Nicole for 9 €, and it seems to be serious stuff. The problem is that it's quite wide, and I'm not sure that it will fit on an archtop semi-hollow - because of the curve... So should I make the change or put it on a solid body with a flat front plate? Still thinking...
