69 BBC Temp switch

I wouldn't call the one in that picture an aftermarket part as much as I would a later generic service replacement to the GM 1969/70 assemby line #19933<span style="font-weight: bold">69</span> sender.
This is one of the misunderstood details out there today,as some assume it's their assembly line sender,when it really isn't.
To be considered assembly line correct,you want the brass one to the far left in this picture,AC #1513130-push on pin,(not screw on),and rated at 248 degrees,from Lectric Lmtd.

The info you posted is good, however those are all &quot;Sending units&quot; that send a variable resistance output ( a thermistor) to a gage.
1993369 is a temp switch only, it is either open or closed to ground the red idiot light. I checked with Lectric Limited and they do not make a temp switch.
The photo I posted and the one Dan posted, I do still believe those are older after market switches made of steel and zinc plated.
I am going to assume that a OEM switch would be brass like the senders are and would most likley look the same.
