I am not not that good at electronics, I am a mechanical kind of guy. I built a stand that uses a linear actuator to move a trap thrower up and down while the trap thrower moves itself from side to side to make it "wobble". My system has 2 momentary switches that set the limits on how far the linear actuator will go and theoretically when the switch is pushed, it will reverse the polarity of the linear actuator until the other switch is pushed and then the polarity switches again and repeats until it is turned off. The guy who I built it for has a DPDT, 12V DC latching relay from Grainger.com that should work, but I don't know much about this relay. I would think that since it is an 8 pin relay, it would have 2 pairs of pins that I could wire the switches to so it would switch the relay. Does anybody know more about these relays and/or have a solution as to how I can do this?
