Welcome to AAC.
It is a bit hard to follow what you are doing concerning the switches so in general terms the best way (absent more information) to do this would be to use a relay to reverse the polarity from up to down, or vice versa. The "normal" direction would be without the relay turned on, the reverse would have the relay on. It requires only one power supply, and will work perfectly.
On the wood strip, you propose an "open loop" system. That is, to depend on timing and not feedback. This is not very good because the wood may not move for some reason and the hatch will try to open anyway. Instead, I would use a limit switch that actually detects the wood in the open position, and enables the power supply to the actuator. If the wood is not up, the actuator won't run, if it is, it will run. This can be done in a complementary fashion disabling the wood movement when the hatch is open as well.
ahh, the problem is that I don’t know how to wire that light switch into everything else, and everything else into that. I was hoping for a diagram for all 4 parts shown here.The paper shows how to connect the 3wire light switch.
Question is, does that light switch work the way you want it, or is it opposite of what you want?
The 3wire for DC is as the paper says, but I guessing that controls the relay some how, then onto the linear motor.
Does the linear move up when connected to batt, then down when you swap leads on batt?
