Starter button help

I bought my 77 KZ750 with only a kickstart, which is all fine and dandy, except while I am working at sorting out some idling issues. I'm wondering if I could install a cheap temp starting button. I've seen little two lead either 6Ah or 10Ah electrical buttons at Home Depot...would either of these work and would one oprion be better than the other? Thanks!

You might want something like a 30 amp switch if its straight to the starter. 20 amp should be good if its to the the starter solonoid...or you could just jump the terminal on the solonoid if the solonoid is broken.
