Product review (5 stars): so I knew it was bad.
It took longer to locate the tools than it did to open the back panel on my Frigidaire range and install this new switch.  It is easier to swap out the wires one by one before you remove the old switch.  Once everything is hooked up, unscrew the old one and screw in the new one.  My burner used to stay on high all the time and then eventually crapped out completely.  The old switch was blackened, so I knew it was bad.
