Aftermarket Turn Signal Switch

I came across a thread regarding aftermarket switches, but can not seem to find it now. So forgive me but I will have to ask something that has been answered a few times over I am sure.....

Located a switch online for $25~ but it has an extra plug. Are the $125 any better than the $25 switch? Any ideas on the extra plug?

What year?
I think from the picture you may be looking for a later one than Dan sells.
Not sure but I think his are for the 60s cars.
I also think that small extra plug on the pictured one is for a key switch which none of my 70s cars has.
Just don't use the plug.
All of the later ones I've found has a cheaper copper piston INSTEAD of the better original style roller horn button pick up.
If anyone knows if a better one is being reproduced for later cars PLEASE post.
