Replaced my ignition switch (again). Will it solve my start problem?, PLUS I awoke the seat buzzer! Options

When I got my 74 1.8 three years ago, it had a new aftermarket ignition switch that went bad immediately. I replaced it with another aftermarket switch but last summer it occasionally would not start, hot or cold. Most recently, I jiggled the key in order to get it to start so I assumed it was the switch again.

So today I replaced the switch with an OEM (Switch Pics in the Parts Vault). But the old switch looked fine. Couldn't detect any cracks, maybe there's internal damage? I had once read about some subtle differences in the switches but could not detect any. Anyone know if the switch can fail and look good externally? This is the fourth switch in the car, including the original, so I'm getting suspicious something else might be wrong.

So I put it together and it starts, but the seat buzzer began to go wild whenever I turned the switch. I went back into the garage later and it stopped! Brad Mayeur had worked on it before I got it and disabled it for me.

Any thoughts appreciated. I want the car more reliable; I've only been able to take short jaunts where I don't have to stop!

A lot of people trash talk the hot start relay. I think there are better looking ones than the ford one but in any case I think they are a good idea. It is nice to know the switch is fairly cheap. I suspect one day they won't be and one day maybe NLA. The hot start relay removes all the load off the ignition switch. Maybe the hot start relay will die but these will always be available in some shape or form. Look how big the wires are going to the switch. This circuit must go from the battery to the steering column and back to the starter. This is a lot of wire and a lot of connections.
