Keyed Mag and Start Switch

[Cameron]

My Eagle kit came with keyed mag switch that also has the start button contacts built in to it. Seems like I've read a few times on this forum that keyed mag switches are not so good in aerobatic aircraft, but I never read why. My ASII had one and it seemed to work fine. Do they eventually wear out and cause and let the key fall out during acro? Or is there something else?

What is the preferred setup? A couple of toggle switches on the P-Leads and a start button would be easy enough to set up.
