series paralell switch
(OP)
I have a 36volt dc motor powered by three 12 volt 60 amp.hr. deep cycle batterys. I want to start this motor on 12 volts, then switch to 24 volts then onto full power to 36 volts. this would give me a "soft start, sort of" how do I connect up the 3 batterys via a 4 way switch. I do not wish to use electronics to give variable speed control.

positive terminal to a pole on the switch, the motor(+)
to the wiper, and the motor(-) to battery negative.
Make sure that the switch is break-before-make, or you
will be replacing it. :)

will have 5 terminals; four of them will be contacts, and
one will be the "OFF" position. The remaining terminal is
the movable contact, or wiper.

You will be overly discharging the low speed battery and the high speed battery won't be discharged as much.
This is why people use speed controls... To NOT thrash their batteries.

If you do intend to persist with the switching scheme, consider using your switch to control power relays rather than bringing high current to the selector. I'd be avoiding anything over a few amps going through the switch. Also check the switch or relay ratings for DC service - DC with an inductive load is particularly hard on the switch or relay. Your low voltage works in your favour though.
