I was hoping that someone can recommend a switch that I can use for my wiper motor.
Here is how the switch needs to work
1) +12v to slow on motor
2) +12v to fast on motor
3) +12v to both slow and fast--this is how my park function works.
That is I need an on-on-on OR on-on-on-off switch but I need three wires to touch in one position (the park position).
Thank you,
Jomo

3 position rotary switch.
Pole 1 through 2 (10 amps total capacity diodes for each motor lead) to each Low and High. Banded end of the diodes toward the motor.
Pole 2 to Low.
Pole 3 to High.
