An ignitor (22) has an outer metal can (24) containing a quantity of reactive material (28) for initiating a pyrotechnic material. A circuit board (36) has a first side that is in contact with the reactive material (28) and a second side that is isolated from the reactive material (28). A well grounded metal structure (40) adjacent the circuit board (36). At least two electrical pins (48, 50) are electrically connected to electrical traces (70,72) formed on the circuit board (36). Electrical discharge gaps are formed by second electrical traces (74, 76) extending from the first electrical traces (70,72) to form sharp points (78,80) which extend to within less than about 0.127 mm of a conductive path to ground. |
