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
