The serration portion 59s of the 59 is held by hand to rotate the viewing window 58 formed on the flange 59 so that the on-marking portion 44 or the off-marking portion 45 on which the switch knob 30 is located. When positioned at, the on-marking portion 44 or off-marking portion 45 is visible through the viewing window 58.

이때 열쇠(20)의 고리부(22)를 스위치노브(30)에 형성된 고리수용부(32)로 집어넣은 다음 스위치노브(30)에 형성된 잠금홀(36)을 통해 밖으로 인출하게 되면, 고리부(22)가 잠금위치선택링(50)에 형성된 관통구멍(54)과 배럴부(42)에 형성된 고리삽입구멍 "42a" 또는 "42b"를 통해 밖으로 인출된다.At this time, if the ring portion 22 of the key 20 is inserted into the ring receiving portion 32 formed in the switch knob 30 and then drawn out through the lock hole 36 formed in the switch knob 30, the ring portion (22) is drawn out through the through hole 54 formed in the lock position selection ring 50 and the ring insertion hole " 42a " or " 42b "

이후 해제되어 있던 고리부(22)를 열쇠(20)에 끼워서 잠금상태로 두게 되면, 열쇠(20)를 풀지 않는 이상 스위치노브(30)가 움직일 수 없게 된다.After the ring portion 22 that has been released is inserted into the key 20 and locked, the switch knob 30 cannot move unless the key 20 is released.

또한, 열쇠(20)의 고리부(22)가 스위치노브(30)에 형성된 고리수용부(32)에 수용된 상태에서 노치부(34)에 걸려서 안착되기 때문에 열쇠(20)가 정렬되어 보다 견고한 잠금 상태를 유지할 수 있게 된다.In addition, since the hook portion 22 of the key 20 is seated on the notch portion 34 in a state in which the hook portion 22 of the key 20 is accommodated in the hook receiving portion 32 formed on the switch knob 30, the key 20 is aligned and more firmly locked. State can be maintained.

한편, 위와 같은 상태에서 열쇠(20)를 풀고 스위치노브(30)를 해방하는 경우에는 열쇠(20)의 잠금을 풀고 고리부(22)를 밖으로 인출하게 되면, 스위치노브(30)가 해방된다.On the other hand, when the key 20 is released in the above state and the switch knob 30 is released, when the key 20 is unlocked and the ring portion 22 is pulled out, the switch knob 30 is released.

이상에서 설명한 바와 같은 본 발명은 종래와 같이 스위치하우징에 형성된 배럴부를 드라이버 등으로 가격하여 구멍을 개방할 필요가 없기 때문에 스위치하우징이 파손될 염려가 없으며, 잠금위치선택링에 의해 스위치노브의 잠금 위치를 쉽게 결정할 수 있도록 구성되어 있기 때문에 사용이 편리하게 되는 효과가 있고, 스위치노브에 형성된 고리수용부와 노치부에 의해 열쇠의 고리부를 일부 은폐하는 동시에 일정한 위치를 유지하도록 구성되어 있기 때문에 열쇠에 의한 잠금 상태를 보다 더 견고하게 유지할 수 있는 효과가 있으며, 잠금위치선택링을 스위치하우징에 조립할 때 잠금위치선택링을 스위치하우징에 형성된 배럴부 안쪽을 향해 단순히 밀어 넣게 되면, 잠금위치선택링에 형성된 탄성후크부가 환형걸림턱에 걸려서 조립되기 때문에 조립이 간편하게 되는 효과가 있다.As described above, the present invention does not need to open the hole by hitting the barrel portion formed in the switch housing with a driver or the like as in the prior art, and there is no fear that the switch housing will be broken. Because it is configured to be easy to determine, there is an effect that it is convenient to use, and it is configured to conceal a part of the key part by the hook receiving part and notch part formed on the switch knob and to maintain a constant position. It is effective to maintain the state more firmly.
