    Abstract: Embodiments of the present invention provide a capacitive switch, an apparatus for transceiving a signal, and a method for manufacturing the capacitive switch. The capacitive switch includes: a first conductive cantilever, a second conductive cantilever, a substrate, and a coplanar waveguide arranged on the substrate, where the coplanar waveguide includes a first conductor configured to transmit an electrical signal and a second conductor and a third conductor that are arranged as ground wires on two sides of the first conductor; an insulation medium layer is arranged on the first conductor, and a conducting layer is arranged on the insulation medium layer; the first conductive cantilever is connected to the second conductor by using a first fixed end, and the second conductive cantilever is connected to the third conductor by using a second fixed end; and when a direct-current signal is transmitted on the capacitive switch, a first free end of the first conductive cantilever and a second free end of the second conductive cantilever contact the conducting layer. In the capacitive switch provided in this embodiment, a stress generated by a metal film bridge of the capacitive switch is released by using a cantilever separate structure, thereby ensuring transmission quality of a signal.
