Product review (5 stars): Problem solved.
The new switch is nice and sensitive, and works just fine.  No more having to slam the lid down to make the washer start!  : )  I do feel compelled to caution people about one of the poster's comments stating that might not need this switch, but can fix the problem instead by bending the metal bar that makes contact with the switch to make it drive into the switch harder.  If there's nothing wrong with the metal bar, just replace the switch.  Otherwise, you are just delaying the inevitable failure of the switch and changing the geometry of the bar, such that when you do get a new switch, the bar will jam in to the switch too far and wear it out faster.  this switch is just too inexpensive to maim a properly functioning part of your washer to make up for it losing sensitivity.  Just put a crowbar in your wallet and buy a new switch for 8 bucks.
