A wireless battery snap without any electrical wires leading out and which has at least one button with exposed metal for use in an electrical device for connecting the battery, making it safer in use. The battery snap comprises an insulating support, conductive eyelets, cylindrical socket and plug electrodes, a spring, a contact plate, an insulating sheet and insulating cover. At least two electrode holes and a protruded base, posts and side walls are provided in the insulating support for securing the contact plate, spring, conductive eyelets and insulating cover. The socket and plug electrodes are held onto the battery snap by two conductive eyelets on the insulating support and fastened together with the spring and contact plate. Two button electrodes of the battery disposed on the socket and plug electrodes respectively are connected to the contact plate on the insulating support and spring or two contact poles. An embodiment of the wireless battery snap uses a set of displaceable electrodes of contact with two independent poles in the electrical device. The spring permanently contacts and depresses on one of the electrodes of the device, when the electrode is displaced, the contact plate connects with the other electrode or disconnects apart therefrom, causing electrical current to flow or stop.
