A switching module comprising a plurality of switching elements, for example, a switch of a P position selected when parking, a switch of an R position selected when moving backward, a switch of N position meaning neutral, There are a switch of L position which means automatic shifting within the range of 1st and 2nd stage, a switch of 3 position which means 3rd stage, and a switch of D position which is selected at the time of normal driving. The select lever position switching unit 10 also includes a start switch S which is turned on by inserting the start key into the start key hole (not shown) and rotating it.

변속레버위치지시등(12)은 복수의 지시등을 갖추고서 상기 셀렉트레버포지션스위치(10)에서 온(ON)된 스위치에 해당하는 지시등이 온(ON)되어 현재의 변속레버의 위치를 알려준다.The shift lever position indicator 12 includes a plurality of indicator lights, and the indicator light corresponding to the switch turned on in the select lever position switch 10 is turned on to inform the position of the current shift lever.

실내등구동제어부(14)는 상기 주차브레이크스위치(1)와 상기 셀렉트레버포지션스위칭부(10)내의 보통주행스위치(D)의 온/오프상태에 따라 실내등(3)을 점등시킨다.The indoor light drive control unit 14 turns on the indoor light 3 according to the on / off state of the normal brake switch D in the parking brake switch 1 and the select lever position switching unit 10.

여기서, 상기 실내등구동제어부(14)는 앤드게이트로 이루어진 논리소자(15)와 스위칭트랜지스터(Q)로 구성된다.Here, the indoor light drive control unit 14 is composed of a logic element 15 made of an end gate and a switching transistor (Q).

즉, 상기 논리소자(15)는 일입력단이 상기 주차브레이크스위치(1)의 일단[즉, 주차브레이크스위치(1)와 주차브레이크 경고등(2)의 사이]에 접속되고 다른 입력단은 상기 셀렉트레버포지션스위칭부(10)내의 D포지션스위치의 일단[즉, D포지션스위치와 변속레버위치지시등(12)의 사이]에 접속된 앤드게이트로서, 상기 양 입력단에 입력되는 신호를 앤드(AND)처리한다.That is, the logic element 15 has one input terminal connected to one end of the parking brake switch 1 (that is, between the parking brake switch 1 and the parking brake warning light 2) and the other input terminal is connected to the select lever position. As an AND gate connected to one end of the D position switch in the switching section 10 (that is, between the D position switch and the shift lever position indicator 12), the signals input to both input terminals are ANDed.

그리고, 상기 스위칭트랜지스터(Q)의 베이스가 저항(R1)을 매개로 상기 논리소자(15)의 출력단에 접속되고 켈랙터는 상기 실내등(3)을 매개로 전원단(Vcc)에 접속되어, 상기 논리소자(15)로부터의 연산신호에 따라 스위칭동작한다.The base of the switching transistor Q is connected to the output terminal of the logic element 15 via the resistor R1, and the chelator is connected to the power supply terminal Vcc via the indoor lamp 3, so that the logic The switching operation is performed in accordance with the operation signal from the element 15.
