Ignition switch Mazda 626

Shortly after buying my Mazda 626, I've experienced occasional troubles starting it. The car just won't react and suddenly, after a few tries, it would eventually start. Whenever it didn't want to start, I couldn't hear anything (not even a relay), which indicated that something was wrong with the ignition switch. I removed it and checked it with my multimeter, but it seemed fine and it didn't look used or broken. Nevertheless, I couldn't think of anything else causing such troubles and I really don't like it when my car experiences starting troubles, and the new ignition switch was quite cheap (around 25 dollars), so I've replaced it and it has solved the problem for good.
