Abstract

PURPOSE: To eliminate the contacts of the speed stage reference switch of an electric transmission for a bicycle or the like and enable safe sprocket shifting operation, by making the switch of a movable electrode plate and plural fixed electrode plates capacitively coupled to the movable electrode plate.
CONSTITUTION: A pulse signal of optionally set code, which is sent out from a signal generator 5, is supplied to a first signal detector 8a through the movable electrode plate 6 of a switch and its first fixed electrode plate 7a capacitively coupled to the plate 6. When a signal supplied to the detector 8a is identified as the pulse signal of set code, a coincidence signal is applied as a speed stage reference signal to a control circuit 9. When the content of the preset signal from a sprocket shifting lever 10 and that of the reference signal have coincided with each other, a stoppage signal is sent from the control circuit 9 to an electric motor control section 11. If the contents do not coincide with each other, a sprocket shifting electric motor 12 is rotated to move the movable electrode 6 to the other fixed electrode plates 7bW7e until the contents coincide with each other.
