Product review (5 stars): Door switch for whirlpool dryer
The part is original, and the price was super cheap.  Every other place wanted to sell me a washing machine switch that was not quite the same but would work with a little modification and about 20 dollars more expensive.  I got this switch for $2.17 and about $4 for shipping from Puerto Rico.  Haven't installed it yet, but I will soon.  Getting original parts for an old dryer is hard.  Oh, the delivery from the island only took 3 days.  Faster than from Ohio to New Orleans.
