Window assembly with solderless electrical connector
A window assembly includes a transparent substrate, an electrical conductor provided on a surface of the substrate, and a solderless electrical connector for energizing the electrical conductor. The solderless electrical connector includes a cover adhered to the substrate to define a hollow volume, and a biasing member disposed within the hollow volume and elastically compressed between the cover and the electrical conductor. The biasing member further being electrically conductive and in electrical communication with the electrical conductor.
