Product review (5 stars): Perfect match for the factory original switch in my Whirlpool washer
I pulled the original part from my whirlpool washer to match the part numbers up.  This replacement is identical to the original.  I don't know yet what kind of life the new switch is going to have but our washer is maybe 4 years old... so I don't expect it to last forever.  I think the flaw in these switches is in the right side (in the picture for the listing) where there is a plastic spring type clip.  I think over the years of the door getting opened and slammed shut (as that happens from time to time) it puts a lot of stress at this one point.  There may be an easy fix to help remedy this (like maybe some super strength tape to keep the whole unit from flexing upward during a slam)... but I'm just going to leave the new switch alone and worry about making it last longer if/when this new one breaks.  On a side note, when my switch originally broke I needed to wash some cloths.  The nice thing about this switch is you can open the cover on it and inspect the parts inside.  So what I did as a "get me by" until my new switch came in was to bridge the connection that the switch performs.  That is, I put a piece of wire between the two points that this connects.  What this does is it makes it to where the switch always acts like the door is closed.  The downside is you can't open the lid to stop the washer to add cloths.  You can still push the main button in and stop it and add cloths that way, but this was a very good workaround for the problem when my switch broke and I needed to find a replacement.  Thank goodness for Amazon for parts like this.  None of my hardware stores locally even carry parts beyond maybe a dryer belt.
