I'm trying to figure out why the switch doesn't turn back after car cranks and it keeps trying to start after but if I slightly touch it myself it will stop. I tried spraying in the switch a few times but sometimes it still does it. I want to know exactly what part do I need to change. Is it the whole switch assembly or a certain part?

Good afternoon,

You will need the switch assembly itself. The issue is internal.
