Fit GREAT ... at a 45 degree angle.
This Switch FIT my 39 year old Sears 60 / 250 Battery Charger.
However there were a ... " FEW " ... adjustments that had to be made.
1. The original hole for the switch to go through the Cabinet , was " OVAL SHAPE " . This new switch , was " Round " and also a little larger. I rounded the hole out and it went right in.
2. When positioning the Switch and Tightening the nut down. The Switch had to be rotated at a 45 degree angle to Align Switch Positions with the " LABEL " on the Charger cover. Also , I ground the little tabs down to make it fit flat. I then just turned the Selector all the way Counterclockwise [ off position ] and then lined it up to the label and tightened down. Works great.
