intermitent wiper switch

Confussed as to how many positions intermitent wiper swich came with in 1970 mustang. According to my owners manual it had a 10 position to the left from off. All switchs that are available are two position, any ideas or help is appreciated. Thanks

Will try to answer my own question. Located a n.o.s. wiper switch which has 10 positions to left and two regular positions to right. Owners manual shows this switch. I can still be corrected if any one knows for sure. I feel this is correct for 1970 mustang.

Thanks for the interest.
