Why do German electrical parts catch fire?

[Ausmartin1]

My First non light globe failure on my VX II after nearly 11.5 years.

The Stop switch made in Germany note how it overheated, melted and seized the plunger with brake pedal at rest.
What is it with GM Eaton Germany (In fact most Germany electrical crappy plastic switches etc? especially on euro cars)

I've never had to replace Japanese stop light switches ever ! (and most look better accessible)

The location of this switch on my VX is a hoot even with the lower dash fuse cover removed, used long needle nose pliers and extended 22mm socket (note hand thread new one first - before using socket again 6mm +/-0.5 gap from hex to screw in plate) another job where bits of trim etc love to give you a little scratch to draw blood.
