Abstract
A switch selectively connects an airbag inflator or a load resistor to a crash sensing module to enable or disable an airbag. A transistor circuit across the load resistor detects whether deployment current is flowing in that resistor. Another transistor activated by the first transistor passes current to a fuse to open the fuse, permanently indicating a deployment event when the airbag was disabled. A latch circuit holds the second transistor on to assure sufficient time to open the fuse by melting.
