Review on RV Toggle Switch: Efficient Control for RV Tank Systems and Heating Pad - Gang Kit Included (3 Toggles) by Dean Gomatham

There is no circuit diagram for the switches, the contacts are simply numbered, all made in China. KIB does not provide a switch pinout, Sigma the switch manufacturer provides a snippet but the same switch has many configurations and there is no part number on the switch so you have no idea. Installing with switch assignments would be easy without risk of messing things up. Please provide correct technical information about the product you are selling.
