Here's a shot from a similar machine that I can get you right now without a new photo. This is from a 1985, fully contented washer with the white basket and the porcelain top. Both use the same console. If you can't read it the options from left to right are: Soak only, soak 'n wash, wash only, wash and 2nd rinse, and finally, soak, wash and second rinse. In that final option, the timer can progress from the beginning of the Pre-soak all the way through the end of the second rinse in cotton/sturdy, uninterrupted.
The Cycle Modifier switch on the left debuted on 1979 90-series models, and it replaced two previous switches used on 1976 thru 1978 machines. It was used to my knowledge on only five models, a 1979 90 series, a 1980 80 series (this differed from the '79 in not having the '79's solenoid operated bleach dispenser), a 1981 80-series, a 1983 80-series, and the 1983/1985 Lady K.
The only model made in huge numbers was the 1983/1985 Lady K. I've never come across the 1979 90 series. I have a 1980 80-series, and have the makings for another (it is there in cabinet and body, but has had a cheaper console transplanted on. Andy has found and sent me the proper console, so that machine may be whole again soon). I have also never seen a 1981 80-series, though VolvoGuy87 has one. This machine is on my dream list. It differs from the 79/80 in having infinte water levels instead of five. All three of these machines lacked the triple dispenser. The 1983 80-series I've never seen either, nor have I ever seen any evidence of one except in the model listings from WP, AND the pictures used in the 1980s Kenmore belt-drive repair manual are of one. This and the '81 are cool because the panel looks like the Lady's presented here, but have the woodgrain on top instead of the textured black.
I never really thought about it, but wow, only five models with that switch, and all were large capacity.
