This ignition switch is a reproduction of the 4-position Lucas Type 149 SA, as used on various makes in the 1970s. The ignition lock complete with keys is included and ready for installation. 

The genuine Lucas 4-position ignition switch is specifically designed to be compatible with the wiring harnesses and circuitry used on many 1970s models. It allows the isolation of the ignition from the lighting circuit. Due to it’s size, it will not fit into the left headlamp mounting bracket of some Triumph models that previously had the ignition switch mounted in that location. 

The Type 149 SA switch has a circuit for running lights only, ignition only, and ignition and all lights. The position of the key in the switch determines which circuits are receiving power from the battery. 

The switch is fitted to the metal right side panel on early oil in frame models. Later models have the switch mounted into a central console between the instruments. Norton Commando models have a bracket on the right side of the motorcycle near the airbox for ignition switch fitment.
