Adding a water level (load size) selector switch to a new commercial Speed Queen?

It's what's called a variable water level control, with a range of choices between minimum and maximum vs. a control with specific levels such as Low, Med, and High.

Photo one is a variable switch.  The cam is a smooth eccentric arc from minimum to maximum (other than typical tiny notches on it to avoid slippage).

Photo two is a three level switch with deeper notches on the cam for each discrete level.

Reset is used to increase the level after agitation starts.  Turn the control to Reset (agitation stops, fill resumes), and back to a desired level that's higher than the initially selected level.  It is not necessary to turn the knob to Reset for selecting a level for the next load before starting the machine, or for changing the level after starting a load if agitation hasn't yet begun.

A Reset function is needed on variable switches because the smooth arc of the cam doesn't otherwise have a way to force the pressure contacts apart to restart filling.  The deeper notches on a fixed-level switch fully depress the actuating lever to reset the pressure contacts each time it's turned from one position to another.

Does a true LWN432SP113TW04 model have a variable switch?

I used part #202937 for the pressure switch. Would a different part# have notches for each of the 4 fill levels?

And while I'm asking questions
Do these pressure switches have the option of turning the screw to change the water amt added for each load size setting? Or are these "hard-coded" into the pressure switch without any option for changing?

Reading Tinytee's post about converting SQ Washer to adjustable water levels instead of buying the pressure switch B12548401 why don't we just leave the one that's in there and cut the 3 wires and solder longer wires on to attach it to the new 2O2937 pressure switch.
Would still have to put tee in to connect the two together . That should work with out buying another pressure switch...don't you think?

That's the way it is supposed to work, it is a variable water level control.

What I was saying is leave the two blue wire on the original pressure switch and extend the three wire to the variable level switch that you buy new
