Removed old switch, installed new switch. During this process the locking tab on the new switch broke off. To complete the repair had to thread a screw through an existing open space in the sheet metal behind and above switch where the locking tab should be located in order to fasten and stabilize the switch in place. Currently appears to be functioning OK. The plastic locking tab is very brittle and will not take any bending adjustment, it will break if you try, and you will be in the same situation as I found myself in. The locking tab is necessary and must be intact to lock the switch in place.
