Hi all,
this is my first post in this forum. I have searched for my topic, but didn't find the answer I was looking for.
I have a linear actuator 12VDC with internal limit switches. Apply power, the actuator will move in one direction until it hit's the internal limit switch, reverse polarity and the actuator moves the other direction until it hit's the internal limit switch. I bought a electronic timer to turn on and off for the actuator at certain times and I bought a DPDT relay from Radio Shack to deal with reversing the polarity. Here comes my problem:
I need a latching relay to tie in with the coil connectors of the DPDT relay, because somehow I need to be able to automatically reverse the polarity every time power is made available by the timer, and as far as I can tell from research on the internet a latching relay will remember the state it is in every time power is applied.
What kind of (reasonable) latching relay would work for me? How would I wire the whole thing together to make it work?
I don't know much about reading electronic schematics, so it would have to be pretty simple for me to understand it.
Thank you for any help,
Hans
