PURPOSE:To simplify the operation and at the same time to ensure the control of an operation mode, by driving the 1oad with push of the 1st momentary switch and at the same time switching the operation mode to release the drive of load with push of the 2nd momentary switch. CONSTITUTION:When the 1st switch 1 is pushed, a relay coil 14 conducts electrically. Then a motor 4 is actuated by a brush L0 to start rotation in a low speed. Thus a wiper is continuously operated in a low speed. Then the switch 1 is pushed again to actuate a relay coil 13, and thus the motor 4 turns in a high speed with actuation of a brush Hi. As a result, the wiper is continuously operated in a high speed. When the switch 1 is pushed again, the motor 4 is reset to the low-speed continuous operation. After this, the 3rd switch 3 is pushed during a low-speed operation, the coil 14 becomes nonconductive to stop the operation of the motor 4. When the 2nd switch 2 is pushed during the nonoperation, the motor 4 has the low-speed rotations for a prescribed of time. Then the wiper works once. |
