    I have a 12v DC linear actuator that I want to do the following:

    When a button is pushed and held down the actuator will move forward (extend). When the button is released the actuator will automatically retract. Basically I want it to sort of behave like a pneumatic actuator. I'm a complete newbie to this and I have no idea where to begin. Here's a link to the actuator I have: http://amzn.com/B00P4U556U

    Any help is appreciated.

    Does it currently have stop limits internal?

    Thanks for the response. Yes there are internal limit switches that are triggered when the actuator is fully extended or retracted.

    You should only need a DPDT push button.
