I received the dryer switch on Oct 27, 2014, the same day the money cleared the bank.  My wife assisted me in quickly installing it.  We tested it; it works wonderfully.  It is important to have this switch on the dryer, to prevent an arm from being destroyed while trying to reach in and get the clothes.  It stops the dryer, like it is supposed to do.  A local appliance store tried to charge us $24. for the same unit.  Keep up the good work.
