I just spoke with Jenn-air/Whirlpool re. this switch. The correct part is no longer available and the up dated part is not a replacement that fits.
They politely said they can't help with the right part.
ANSWER Hello Brian. To install the switch, you will need to install the holder with the switch W10341820 as well. Hope this helps.
