Hello all,

I am making a linear actuator that I would like to auto forward/rev indefinitely until powered off. I've seen many posts and videos, but being a beginner student/hobbyist, I am having trouble understanding the wiring and concept.

I've read this can be accomplished using 2 limit switches (one at each end of the actuator cycle), 2 diodes, and a fwd/rev relay module like this? (https://rb.gy/m14d2). I'm not sure how this all connects. This is my first real electronics project beyond wiring a DC motor to a 12v battery.

Any help would be greatly appreciated. Thank you for reading.

Welcome to AAC.

The module you have selected will work and is easy to wire. This is the diagram you want:

​

The forward and reverse switches will be your limit switches. If you have any questions, just ask.

 

What is the current rating of the actuator?

 

Thank you Ya'akov MaxHeadRoom for your replies.

This is a DC motor I had on hand: https://shorturl.at/chmrF
And I'm using a 12v battery: https://shorturl.at/fCNQ3

Waiting on a couple of parts today (the lead screw/threaded bar mainly) to build the core actuator.

I've started a wiring diagram to get things going, but I get stuck on what to do next...
