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.
