I recall posting here a while back about the same thing. Looks interesting
what you came up with.
For sure don't use this. I posted it here:

IMHO, it's a risk to have that heat near wires under dash. You may find the
same issue with the heat sinks on the switch you point to though I'm
certainly no expert! :)

Basically between the list and my own thoughts, I figured it was just fine
to use the stock switch. Yes it eventually fails, but IIRC, they can be
found for not a lot of money.

I had thought that one could use a DPDT "on-off-on" switch. Like a real HD
one. Only two speeds, but why not just have med/hi or low/hi only?

Just a thought,

Neil.
