Product review (5 stars): the good reviews are accurate
thanks to those that provided reviews- those that described the 'switching' of the switch-  My subzero 680 started to go, then went completely.  After reading the reviews I made the purchase and completed the job in about 5 minutes-  pulled the grate back and disconnected it from the hooked springs, disconnected the 2 wires, by hand, from the switch, used a needle-nose pliers to snap the side-tab back and the old switch dropped right out; pushed the new one in and it snapped right into place, reconnect the 2 wires to the switch connections by hand and that was it.  What I'm told would've been a $150 maintenance call resolved for about $8. Thanks guys.
