SQUIB CIRCUIT CONNECTOR LOCK SWITCH
The switch is a mechanism that shorts the power
supply terminal to the ground terminal automatically
in the air bag squib circuit when the connector is dis-
connected. A "short" spring is integrated inside the
connector. This spring prevents static electricity from
flowing to the squib by shorting the power supply ter-
minal to the ground terminal (i.e. there is no potential
difference between the two terminals).
CAUTION
When the connector is disconnected, there will
be short circuit between the terminals. This is not
a fault.
