Abstract

When a key is inserted into a key cylinder and a key insertion switch switches from an open state to a closed state, a signal is provided to a main relay controller. This main relay controller provides a low level signal to a base of a first transistor to actuate a coil. Therefore, a contact point is closed and power is supplied to an anti-theft controller and an engine controller. Thus, these controllers do not consume power until the key insertion switch is closed and thus, their construction can be made simple since there is no need to operate them in a sleep mode.
