    Hi. Newbie here, and someone who is completely ignorant of electronics. I am trying to open and close a small door with a linear actuator that is triggered by a snap action switch. So when the small auto pulls into the garage, it depresses the switch which retracts the actuator closing the door. And when leaving the garage, the switch is released which extends the actuator opening the door. I have no idea how to wire this. Can anyone help? A wiring diagram would be a great help. Do I need any other components?

    By the way, the small auto is a robot lawn mower. I built a garage for it and need a door... Thank you!

    Closing the door once the mower is home in its base station should just require the mower to push on a switch, or break a light beam.
    The same switch could also open the door when the mower starts to move, but there is a risk that the mower will hit the door before it fully opens.

    Any chance of a few photos?

    No photos as I haven't put the door in yet. However, if you look at this short YouTube video, you'll see near the end how it will work. But I still don't know how to wire it.

    Thanks!

    Will be rather dangerous if the door is not fitted with "load" or "limit" switches.
    Does the door need to open from the outside..?
