The bridgewire is a heating element, typically in the form of a loop or coil of thin wire, which is encased in the pyrogen, which is a quantity of readily ignited pyrotechnic initiator composition.

The "test" button on a firing system typically tests the system by sending a current limited to well below the no-fire current (often 200 mA), to allow for detection of common problems such as short circuits and disconnected open circuits.
