The Buckethead approach to killswitches is to literally have a "push-to-make" button that connects the hot and ground signals when held down, muting the signal. However, I don't find this very useful, so am going for the reverse of that, ie: the guitar goes BLARGH when the button is pressed and held, silent otherwise. I'll put a microswitch in to allow "normal" playing too, like so:

As it turns out, I don't believe the neato colourful-n-sturdy arcade buttons come in 'push to break' format, which is disappointing for mah plan.
Basically what I'm asking is; is there any neat way (ie, by using more components, not modding the switch) to covert a 'push-to-make' into a 'push-to-break'?
