Hi ! Welcome to IRV2! We're sure glad you joined us!
Are you using a voltmeter to check for voltage on each side of the switch?
I would suggest that you create a signature showing the make and model of your RV. It will help folks to answer questions you may have in the future. Look at post #30 in the link below that tells you how to do that.

Good luck, happy trails, and God bless!
