A lamp refining an earlier design of lamps #35 and the Stereoviewer lamp.
The switch uses the same pull chain mechanism by dowel I used on #38. I found it to be a more simple and reliable mechanism than the one used in previous similar designs (at right) which used a rotary switch with a dowel threaded onto the end. These rotary switches could also only be activated when turned clockwise, while the pull chain mechanism could be activated by turning either direction.
The back end of the dowel switch is flush with the back face of the lamp.
