A switchboard having a position-indicating apparatus for indicating a position of a transformer or a circuit breaker, wherein the position-indicating apparatus comprises: a case; and a position-indicating unit provided at the case and being rotatable to indicate a test position or an operation position of a truck, on which the circuit breaker or the transformer is mounted; characterized in that the position-indicating apparatus further comprises: a rotation member provided in the case and connected to the position-indicating unit to be rotatable in response to rotation of the position-indicating unit; and a rotation-adjusting member provided in the case, located between the rotation member and the truck, wherein the rotation-adjusting member comprises: an adhesion pin disposed to protrude toward the truck; and a rotation plate coupled with the adhesion pin, the rotation plate including a first rotation-adjusting plate provided at one side thereof and protruding toward the rotation member, and a second rotation-adjusting plate provided at another side thereof and protruding toward the rotation member, wherein a truck cover is provided at a front surface of the truck, wherein the truck cover pushes the adhesion pin and the first rotation-adjusting plate accordingly protrudes toward the rotation member, such that the rotation of the rotation member toward the operation position is restricted by the first rotation-adjusting plate, in case where the truck moves to the test position, and wherein an adhesion between the truck cover and the adhesion pin is released and simultaneously the rotation plate rotates so as for the second rotation-adjusting plate to protrude toward the rotation member, such that the rotation of the rotation member toward the test position is restricted by the second rotation-adjusting plate, in case where the truck moves to the operation position, wherein the rotation-adjusting member prevents the rotation member from rotating to the operation position when the truck is located at the test position, and wherein the rotation-adjusting member prevents the rotation member from rotating to the test position when the truck is located at the operation position. a case; and a position-indicating unit provided at the case and being rotatable to indicate a test position or an operation position of a truck, on which the circuit breaker or the transformer is mounted; a rotation member provided in the case and connected to the position-indicating unit to be rotatable in response to rotation of the position-indicating unit; and a rotation-adjusting member provided in the case, located between the rotation member and the truck, wherein the rotation-adjusting member comprises: an adhesion pin disposed to protrude toward the truck; and a rotation plate coupled with the adhesion pin, the rotation plate including a first rotation-adjusting plate provided at one side thereof and protruding toward the rotation member, and a second rotation-adjusting plate provided at another side thereof and protruding toward the rotation member, wherein a truck cover is provided at a front surface of the truck, wherein the truck cover pushes the adhesion pin and the first rotation-adjusting plate accordingly protrudes toward the rotation member, such that the rotation of the rotation member toward the operation position is restricted by the first rotation-adjusting plate, in case where the truck moves to the test position, and wherein an adhesion between the truck cover and the adhesion pin is released and simultaneously the rotation plate rotates so as for the second rotation-adjusting plate to protrude toward the rotation member, such that the rotation of the rotation member toward the test position is restricted by the second rotation-adjusting plate, in case where the truck moves to the operation position, wherein the rotation-adjusting member prevents the rotation member from rotating to the operation position when the truck is located at the test position, and wherein the rotation-adjusting member prevents the rotation member from rotating to the test position when the truck is located at the operation position. an adhesion pin disposed to protrude toward the truck; and a rotation plate coupled with the adhesion pin, the rotation plate including a first rotation-adjusting plate provided at one side thereof and protruding toward the rotation member, and a second rotation-adjusting plate provided at another side thereof and protruding toward the rotation member, wherein a truck cover is provided at a front surface of the truck, wherein the truck cover pushes the adhesion pin and the first rotation-adjusting plate accordingly protrudes toward the rotation member, such that the rotation of the rotation member toward the operation position is restricted by the first rotation-adjusting plate, in case where the truck moves to the test position, and wherein an adhesion between the truck cover and the adhesion pin is released and simultaneously the rotation plate rotates so as for the second rotation-adjusting plate to protrude toward the rotation member, such that the rotation of the rotation member toward the test position is restricted by the second rotation-adjusting plate, in case where the truck moves to the operation position, wherein the rotation-adjusting member prevents the rotation member from rotating to the operation position when the truck is located at the test position, and wherein the rotation-adjusting member prevents the rotation member from rotating to the test position when the truck is located at the operation position.
