Starter holes were made 3/4" (20mm) away from the channel and 4 3/4" (115mm) from the edge on each side of the channeled pieces. This hole was to mount the first #4 (2.5mm) screw. The enclosures were partially disassembled but the most important part was to remove the plastic as this allowed a short screwdriver to be operated from the top with less interference from the braces mounted at the bottom. The cross-member was removed from one enclosure but this was unnecessary.

First screw installed on switches

Once all the switches were mounted with a single screw, and able to rotate, the plastic was reinstalled. The top of the plastic was pushed to simulate a button press and the switch was rotated into position to ensure a switched state. Once the correct position was found a second screw was installed. Some of the switches still needed adjustment after the second screw. This was done by bending the lever arm slightly until a more reliable action was evidenced. The switches were tested with a digital multi-meter (DMM) set to measure continuity.
