ABSTRACT:
A method of making an explosion proof contact assembly and the resulting contact assembly are described wherein the electrical contacts are first rigidly mounted on a contact unit or subassembly prior to the molding operation. This approach allows complete assembly of the contacts prior to molding of the contact unit within the insulating body, while maintaining required flame path for explosion proof atmospheres. The present invention eliminates post-molding assembly operations which are extremely difficult and substantially raise the cost of producing the contact assemblies.
