本考案はかかる点に鑑み考案されたものにして以下本考
案の一実施例を図面に基いて説明する。The present invention has been devised in view of these points, and one embodiment of the present invention will be described below with reference to the drawings.
第１図は本考案によるモータ回路図である。FIG. 1 is a circuit diagram of a motor according to the present invention.

１との間に夫々白熱球４，５が介挿される。In this figure, 1 and 2 are DC power supply terminals, and 3 is a changeover switch with 1 circuit and 3 contacts L, 1'J, and R. The movable piece M of the switch is directly connected to one DC power supply terminal 2, and the changeover switch 3 Incandescent bulbs 4 and 5 are inserted between the pair of fixed contacts L and R and the other DC power supply terminal 1, respectively.
該白熱球及び切換スイッチ３は制御ボックス６に取付け

段１１を介して音量調整ボリウム１２を回動せしめる。Reference numeral 7 denotes a controlled object such as a car radio, and both ends of a DC motor 8 housed in the controlled object are connected to a pair of fixed contacts L and R via lead wires 9 and 10, and the DC motor 8 has a 1,000-speed variable speed. 11 to rotate the volume adjustment volume 12.
以上の構或において第１図状態においては、スイッチ可
動片Ｍが中性固定端子Ｎに接続されているので、直流モ
ータ８は非給電状態にある。In the above structure, in the state shown in FIG. 1, since the switch movable piece M is connected to the neutral fixed terminal N, the DC motor 8 is in a non-power-supplied state.
この状態でスイッチ可動片Ｍを一方の固定端子たとえば
Ｌに接続したときの回路を第２図に示す。FIG. 2 shows a circuit when the switch movable piece M is connected to one fixed terminal, for example L, in this state.
この図において一方の白熱球４が直流電源端子１，２に
接続され、他方の白熱球５と直流モータ８の直列回路が
一方の白熱球４に並列接続される。In this figure, one incandescent bulb 4 is connected to DC power supply terminals 1 and 2, and a series circuit of the other incandescent bulb 5 and a DC motor 8 is connected in parallel to one incandescent bulb 4.
従って直流モータ８は他方の白熱球５を介して給電され
て左回転し、一方の白熱球４は直流電源の全電圧が印加
されて点灯し直流モータの左回転を表示する。Therefore, the DC motor 8 is supplied with power through the other incandescent bulb 5 and rotates counterclockwise, and one incandescent bulb 4 receives the full voltage of the DC power source and lights up to indicate that the DC motor is rotating counterclockwise.
この場合に他方の白熱球５は直流モータ８と直列接続さ
れているので、分圧電圧が印加されることになり、点灯
していない。In this case, since the other incandescent bulb 5 is connected in series with the DC motor 8, a divided voltage is applied to it, so it is not lit.
この状態で直流モータ８が左回転してボリウム１２を回
動し、スイッチ可動片Ｍを中性固定接点Ｎに切換えるこ
とにより所定の音量を得ることができる。In this state, the DC motor 8 rotates counterclockwise to rotate the volume 12 and switch the movable switch piece M to the neutral fixed contact N to obtain a predetermined sound volume.
ところがスイッチ可動片Ｍの切換えが遅れた場合、ボリ
ウム１２は終端に至り、回動しなくなる。However, if the switching of the movable switch piece M is delayed, the volume 12 reaches its end and stops rotating.
このため直流モータ８は過負荷状態になり、過負荷電流
が他方の白熱球５及び直流モータ８に流れて他方の白熱
球５の電圧降下が大きくなる。As a result, the DC motor 8 becomes overloaded, and overload current flows through the other incandescent bulb 5 and the DC motor 8, increasing the voltage drop of the other incandescent bulb 5.
従って該白熱球５が点灯して直流モータ８の回転終了を
表示すると共に白熱球５のフィラメント抵抗が自己加熱
により大きくなり、直流モータ８に流れる電流を小さく
し該直流モータの焼損を防止する。Therefore, the incandescent bulb 5 lights up to indicate the end of rotation of the DC motor 8, and the filament resistance of the incandescent bulb 5 increases due to self-heating, reducing the current flowing to the DC motor 8 and preventing burnout of the DC motor.
尚スイッチ可動片Ｍを他方の固定端子Ｒに接続した場合
には、直流モータ８は右回転し、他方の白熱球５が点灯

タ８に流れる電流を小さくシ、該直流モータの焼損を防
止する。When the switch movable piece M is connected to the other fixed terminal R, the DC motor 8 rotates clockwise, the other incandescent bulb 5 lights up to indicate clockwise rotation, and when the rotation of the DC motor 8 ends, one side rotates clockwise. The end of the rotation is indicated by the lighting of the incandescent bulb 40, and the increased filament resistance of the incandescent bulb 4 reduces the current flowing to the DC motor 8, thereby preventing burnout of the DC motor.

できる。As described above, according to the structure of the present invention, the one of the pair of incandescent bulbs that is not connected in series with the DC motor becomes the rotation direction indicator light of the DC motor, and the circuit structure is extremely simple. The other incandescent bulb connected in series serves as a rotation completion indicator when the DC motor completes its rotation, and its increased filament resistance suppresses excessive current flowing through the DC motor, thereby preventing burnout of the DC motor.
