ABSTRACT:
A circuit continuity test device is disclosed. The device utilizes a series circuit to provide a completed circuit for an external explosive or pyrotechnic circuit. The series circuit has a switch in the form of a light emitting diode and a power source. Upon coupling to a continuous external circuit, the diode is placed in an on state thereby illuminating and indicating a continuous external circuit.
The device housing is a simple, compact and solid part. This allows the device to be used in a variety of environmental conditions and easily and inexpensively manufactured.
