dpdt switches
« on: September 15, 2003, 05:22:29 PM »

are power winows switches and door lock switches dpdt. ford uses switching polarity and instead of having to cross wires to lower window would a dpdt switch work?  two wires from the window motor and a power and ground from the dash a total of 4 wires but the switch has 6 terminals?



thanks

I would guess they used a DPDT switch.  A DPDT switch has legs set up like this:

Code: [Select]

o o o
o o o

first position
o-o o
o-o o

second position
o o-o
o o-o

so you could probably wire it like this, reversing the polarity at each position:
                     +
to motor + lead <--o o o--> to motor - lead
to motor - lead <--o o o--> to motor + lead
                     -

would this work with the middle terminals empty?

nope.  the middle terminals connect to either the left or right terminals.  The outer terminals will never be connected to each other from within the switch.
