Patent attributes
A component for a human-powered vehicle basically comprises a power source connecting portion, an actuator and a first electronic controller circuitry. The power source connecting portion is connected to a power source. The power source connecting portion includes an attachment surface, a first terminal and a first detection terminal. The actuator is electrically connected to the power source connecting portion. The first electronic controller circuitry controls the actuator with supply current provided from the power source. The first terminal is electrically connected to a power supply terminal of the power source. The first terminal supplies the supply current to the actuator in a state where the first detection terminal is electrically connected to a second detection terminal of the power source. The first detection terminal contacts to the second detection terminal after the first terminal contacts to the power supply terminal during connecting operation of the power source to the power source connecting portion.
