Does anybody know if the limit swithes are closed or open when contact is made.
EXAMPLE; fully extended, Closed or Opened?:confused:

I think you'll have to provide a link to the part for any sort of help.

While the limited documentation does not say what the switches are. Based on the video, which mentions the linear activator has only having 2 wires:
Each end most likely is a NC (Normally Closed) Switch with a diode across it. When the unit reaches its end of travel it opens the switch, which drops the diode in. This shuts the unit down till the current flow can be reversed.

Fully extended, open with a diode across it (diode one way valve for current).

Best guess :)
