Inter-lock switchINTER-LOCK SWITCH
The inter-lock switch is a switch provided in order to prevent
sudden movement of the vehicle when the engine is star-ted.
BTAFTER YCTER
If the Clutch Pedal is Not Depressed:
Because the inter-lock switch is switched ON when
STABT
position, electricity flows from the cloil of the starter
relay, through the inter-lock switch, to ground. As a
?sult, the contacts of the starter relay separate,
vitching it OFF, and the starter motor is therefore
not activated.
