Hi, not being a Datsun owner I am not familiar with the action of a Wiper Switch I bought from ebay.
I was told it was a 120Y switch that had an Intermitant setting Plus two speed and a water spray.

It twists then pulls out to two positions.

This is the description from the ebay listing:
"You are looking at a datsun 120Y coupe sedan or wagon Wiper switch assembly In excellent condition. this part looks almost new and comes with the control knob. I think this switch is an intermitent wiper switch as it has a balast resistor down 1 side.this has been stored for 20 years and was stored as a good working unit. The best you could ever get. "
can anybody help?

I can send you a photo of it if you send me your email, as I cannot load a picture on this thread. (please somebody tell me how!)Thanks Oli

I have never seen one with intermitten wipers.

the twist is for the spray and the two "pull" settings for fast and slow.

Mike the twist is a set position not a momenary thing and you can't access the two pull out positions until the twist has been set (?) Confusing.

From the pic, you appear to have scored yourself a headlight switch with dashlight dimmer and the added bonus of it being fitted with a wiper knob.

Thanks Steve,
What are the positions, would'nt you normally have just Parkers and low beam, but whats the third possi?

Sorry just saw the comment about ldash light dimmer, but this is not the case as theey are all SET positions,

Once you pull it out the 2 positions, can you once again twist the knob?

Yes, you can but it is also a FIXED position, NOT a momentary action.
