[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a circular electric switching switch for forward, reverse, and stop of a motor or the like by operating a string.

[0002]

[Prior art]

 Conventionally, the electric switch of the animal toy is provided on the abdomen in relation to the battery box, and an on / off switch is generally used.

[0003]

[Problems to be solved by the device]

 In the conventional electric switch for toys, the switch part is operated directly on and off. Therefore, for example, in animal toys, there is a switch on the abdomen where the limbs are actively activated from the position where the battery box is arranged, and that portion must be operated, which could lead to being caught in the limbs. To avoid such dangers, animal toys are required to operate a tow rope and operate an electric switch.

[0004]

[Means for Solving the Problems]

 An electrode switching slide body that moves relative to the base is provided, and a pullback spring is connected to this slide body to urge it to hold it in a fixed position, and a pulling string that moves in the opposite direction is connected to allow pulling movement. The movable body is provided with an operating shaft, and a movable switching support plate consisting of a saw-tooth guide hole and a return guide hole into which this operating shaft fits is installed side by side. Sequentially limit the amount of movement of the operating shaft that can be pulled up to the upper stage side with a pull cord at the same time, hold the pulling position, and freely descend from the return guide hole from the uppermost stage to the lowermost stage. It is a circulation type electric changeover switch for normal rotation, reverse rotation and stop of a toy motor by string operation, which is operated by operating a moving body to circulate and switch the electric circuit such as OFF, forward rotation ON and reverse rotation ON.

[0005]

[Operation] When the electrode switching slide body is pulled up by the action of the drawstring with respect to the base, the contact surface between the electrode on the base and the contact plate of the electrode switching slide changes and the forward rotation, reverse rotation on, and stop occur. The connection changes. The operating shaft of the electrode switching slide body that fits into the sawtooth guide holes of the movable switching support plate that is installed in parallel with the electrode switching slide body is stopped and connected at each connection electrode position in response to the pulling operation. Loosen the drawstring to move the operating shaft to the stop bearing surface, which is supported at that position to hold the contact position between the electrode and the contact plate. When the drawstring is loosened in the uppermost stage, the operating shaft fits in the return guide groove, becomes free, returns to the lowest position, and is fitted again in the sawtooth guide hole. Operate.
