Mounting switch to the pop out panel
Mounting the switch in the knockout panel.
The switch is sized to fit in the smallest of the cutouts. The 1/4" hole needs to be centered pretty well if the switch is to fit between the two mounting tabs. It is a good idea to center punch the middle, or use a small center drill. Assemble the switch with one nut, and the star lockwasher on the inside. Hold the stitch straight while snugging up the nut. This only needs to be tight enough to prevent rotation.
