Hey RD. The Replacement Extend/Retract Switch item # LC49MD is not going to work with your Libra 3500 lbs electric jack. It's got four pins and it looks like your jack switch needs five or six.
We don't carry Libra jacks and there's no replacement part information on their website. You could try the Replacement Extend and Retract Switch for Bulldog Powered Drive A-Frame Trailer Jacks item # BD500363. It's got six pins and is labeled identically. It's designed for Bulldog jacks but it might work with your Libra.
I have linked a schematic below for the item # BD500363 that shows the functions of the pins.
