ROTARY SWITCH ON/OFF LUCAS
Lucas rotary on/off headlight switch, PN 31356, for A.C. magneto ignition and direct-lighting electrical systems.
This is the Lucas rotary on/off switch that shows up in the electrical equipment figures for magneto-ignition, direct-lighting setups, PN 31356, also catalogued under WW11029L. It's the switch you turn to bring the lights on and off on bikes running the older A.C. magneto ignition and direct lighting arrangement rather than a battery-charging system.

On these machines the lighting circuit is fed straight off the magneto's AC output, so the switch controls whether current gets routed to the lamps at all - there's no battery buffering it. It's a simple rotary unit, the kind mounted where the rider can reach it to click the lights on for running after dark and off again to save the bulbs and coil.
Our catalog record ties this one to the 1963-1967 span with several appearances across the direct-lighting and magneto ignition figures. If your bike runs a different lighting or ignition setup than what's shown in those figures, give us a call and we'll confirm before you order.
