Hello new here and kind of with electronics to, but I can get by. I have a 12 volt linear actuator with limit switches built in. I have a momentary rocker switch that I want to switch the pularity everytime the button is pressed. Basically press the button and it opens the door, press the button again and closes the door. I’ve seen things online(in forums) but can’t really wrap my head around it, but I’m sure it’s not hard, something like a latching relay maybe, I just don’t know where and what to get? Any help would be awesome.
