Is it electrical?

In November, I emailed about my 1992 Ford Escort LX with 182,000 miles. My problem is my ignition switch needs replacing about three times a year. Your suggestion was to replace the neutral safety switch which I did. Shortly, thereafter, the ignition switch had to be replaced and I thought maybe it was damaged from the pre-installation of the new switch. Lately, the ignition switch is starting to act like it will need replacing again. Put the key in the ignition and nothing, and on the second attempt the engine kicks over. It is only a matter of time until I put the key in and nothing happens. The ignition switch does come with a 12 month, 12,000 warranty but it isn't the ignition switch in my thinking. It is something else. With the neutral safety switch replaced, any other suggestions. While I am prolonging the inevitable, I really am not ready to purchase another car right now. Thanks.
