I have this linear actuator.

 It has 2 wires, and the chassis is not grounded. It has no limiting switches internally. I need to find a diagram, but googling so far has not got me very far. Of course I know little about electric thingys so I dont even know what to type in for keywords.

 I need to use this on a Vicon spreader to open and close the feed. I also need to use a "maintained" action toggle switch so that I can simply toggle one way to open, and the other way to close.

 Where can I find wiring diagrams for limit switch installation to stop the actuator at one point in one direction, but still get it to work going the opposite direction, with only a 2 wire motor and no grounded chassis?

 Thanks for any help.
