Abstract
A walk-substituting cart includes a body, a steering head member, a power device, and a switch to switch on the power device; the switch includes a mother board fixed in a hollowness of an uppermost portion of the steering head member, a dip switch on the mother board, a card reading member fixed behind the mother board, and a key card matching the dip switch; the dip switch is electrically connected to the power device; the card reading member is connected to the dip switch; the key card will close the circuit of the dip switch, and in turn the dip switch will turn on the power device of the cart when the key card is inserted in the card reading member; the original controlling mechanism of the power device doesn't have to be altered to allow the key card operated switch to be installed to serve its purpose.
