I stumbled across this item the other day, which looked really familiar.
Electric Power Window Master Switch For Toyota 2004-2009 Camry Sienna
Lees than $25, free shipping. Buying genuine is a guarantee of something meeting the grade. Non-genuine might or might not be, but with global parts sourcing a reality now the factory making a part that some might consider to be a knock-off might be doing that because they're the actual source of an OEM part. Then again, maybe not. Got no idea here. Some parts are critical, I spent $175 on a couple of front brake lines from Mr. T the other day, but those are mission critical. A window switch? not so much so long as it works right and plugs up. My original is working fine and very well could continue doing so, which does say smething about relative value and the time it takes to make your investment in whatever parts you buy pay off.
