You can use the swich you have if you go to the solenoid 2 small wires and leave the yellow/red where it is but change the other small solenoid wire to an earth and not a power, also make sure all the blacks from the rh switch are connected to black in the headlamp.
All you are doing is powering the solenoid instead or grounding it

Cheers Oddjob, Im going to see what else Ive got.

The thing that threw me was the thing works when grounded .
 It looks to my non electrically trained mind that the solenoid gets power from the small black wire and the yellow/red is earthed when the switch is pushed, thereby creating a circuit.
 My switch (550} has an extra wire from clutch lever switch (to stop in gear starting without clutch, I think) I reckon I could use this switch by making it earth and doing away with the black "safety" wire. Anyway what could possibly go wrong.
