Has anyone used a Delta Hazard switch ?

I'm puzzled how to use it as on the OFF position pins 1 and 2 are connected and 3,4,5,6 are open
In the ON position pins 1 and 2 are open and pins 3,4,5,6 are all connected together.

There seems to be no provision for changeover from switched ignition 12V to permanent 12V.

Update - nice people at Europa say it's an Austin Mini switch (AUSTIN ?? ) so it's off to the library

If it's the same as the mini switch I think the wiring diagram you want is here

Thanks Ian. Looks as if I have to fit separate indicator and hazard flashers
