I'm not fond of the inline cable switches most commonly found on bedside lamps and lamps in general as well as some other electrical items. They dangle off the side of the table, often hard to find in the dark and are nearly always too low to reach comfortably.

I recently added another device next to my bed so now requiring two of these switches one of which would have been on the floor or draped around the bedlamp to be able to find it, so I designed an enclosure for them which can be bluetacked or double sided taped to the bedside table and easily located even in the dead of night.

The enclosure is designed with the main cable entry slots in line with the switch and then multiple exits for routing the outfeed side of the switch to where you want it to go - ie: the cable can tuck alongside the switch and exit the bottom or either side of the enclosure.
There is also a cover which snaps over the enclosure basically to assist keeping the switches aligned and tidy it up a bit.

I use ABS.
