Product review (5 stars): Easy to replace and works just like new!
This switch is an exact replacement for the STOP START switch for our Whirlpool trash compactor.  It took about thirty minutes to change the switch.  You need to pull the compactor out, disconnect the power to the unit, open the compactor, turn the run-lock switch to LOCK.  Then remove 2 small screws under the front start-stop-run switch face plate, gently pull up on the face plate and you will see the back of the switch.  Note the wire color positions, pull the wires off, remove 2 screws.  eplace the switch with the new switch and reinstall in the reverse.  Works like new!
