An electrically-conductive epoxy resin is disclosed having stable joint resistance over extended operating times and high impact strength where the resin is based on a silver flake-filled polymeric reaction product of a liquid bisphenol A having very low hydrolyzable chlorine content and suitable polypropylene oxide-based primary amine curing agents.

Conductive epoxy adhesive

An illuminated elastomeric keypad switch assembly has an optical conductor on which a printed circuit is printed via electrically conductive ink and a keypad provided with translucent areas for passage of light. The optical conductor has recesses located adjacent the key caps whose width and depth progressively increases proceeding from the closest to the farthest key cap from a light source so that a uniform amount of light is transmitted through the key caps.
