hey guys, this is my first post here.
I have a DPDT latching relay. It has 8 pins and I need help figuring out how to wire it up. What I want to do is set up some relays or something to make my momentary switch trigger the relay to up or down. I want to use a momentary switch instead of a rocker switch because a rocker switch wont fit in the area I am installing it into.
My Relay looks like this:
1 2
3 4
5 6
a b
Pin A and B are positive and negative.
Pin 5 and 6 are the common pins.
Pin 1 and 3 are what is switched with Pin 5.
Pin 2 and 4 are what is switched with Pin 6.
How can I wire up some relays or wire this up so that i have a Momentary switch make A positive and B ground on the first pulse, then make A negative and B positive on the second pulse??
Um......
Changing the polarity to the relay coil isn't going to make anything change direction. You have to change the polarity of the wires going to the device you are trying to control (the wires on teh contacts).
Good luck.

What you'll need is two separate DPDT relays, one for up, one for down.
Then, you'll need a control system of some sort, if you want to use a single momentary switch you'll have to figure some stuff out (like whats going to happen when the window or whatever gets to the end of its travel). It doesn't sound like you are planning on using any shutdowns that would safely break the latch to prevent the motor from binding up.
Then, you can work on integrating the one switch in to the up and down portions of the system. I'm sure it could be done with all relays, but I would use a simple digital circuit to toggle the one switch to the two different outputs.
