ABSTRACT:
A switch actuator assembly comprises an insulating base and an insulating retainer assembled therewith. A switch contact assembly initially includes at least a first contact and a second contact interconnected by an integral narrow strip of sheet metal. The base and retainer are provided with an integral punch and die, and during assembly of the switch contact assembly with the base and the retainer the punch and die sever the connecting strip so that the first and second contacts are thereafter electrically isolated. During such severing the strip is deflected from its initial plane to augment the electrical isolation.
