Yes you are correct Brian - it pulls to turn on the lights and twists to increase the strength of the back-lighting in the dials. I also think you are right Richard in saying that your switch, would turn on the lights but not work as a dimmer for the dials. Many thanks anyway.
The instrument lighting brightness is controlled by one of the chrome rotating knobs? In the lower part of the dash below the instruments.
The first pull of the lighting switch turns on the inner head lamps, then if you push the indicator stalk forward, it puts out the headlamps and leaves you on sidelights only, frightening the first time you do it by accident on an unlit road.
Pulling and twisting the switch to the right turns on the outer headlamps, and the indicator stalk is used to dip them or put them onto main beam, the inner headlamps stay on when the outers are in use.
