A suspension lamp includes a switch box, a wire connection base, a circuit board, a power supply wire, a plurality of protective jackets, a plurality of connecting terminals, and a plurality of electric wires. Thus, the operator only needs to insert each of the connecting terminals into a respective one of the protective jackets so as to form an electrical connection state, so that the electric circuit of the suspension lamp is connected easily and conveniently, thereby facilitating the operator mounting the electric circuit of the suspension lamp.
