Two Speed Wiper Switch

[newbe351]

Anybody make a decent two-speed wiper switch? I'm on my third one now. The last one had the backend blow out and it took a while to figure out all the springs, washers, etc. to get it back together and the back crimped on tight. It worked for a while but now it doesn't "park" when you turn it off.

Are they all pretty much the same and just buy a couple to have a spare on hand, or is there a decent replacement part available?

Thanks
