Car won't start

I have a 1996 Toyota Camry with 115000 miles. Recently, I turned the key and nothing happened, no sound, nothing. I turned it again, and it started fine. This has happened 5 or 6 times in the last 3 weeks. What might be going on?

The first thing to do is remove the battery cables and the clean the connections using a battery brush. If that doesn’t solve the trouble then check wiring to the main power panel along with the ignition switch connections.

and the ignition switch.
