A microelectromechanical system (MEMS) switch comprising a radio frequency (RF) transmission line; a structurally discontinuous RF conductor adjacent to the RF transmission line; a pair of cantilevered piezoelectric actuators flanking the RF conductor; a contact pad connected to the pair of cantilevered piezoelectric actuators; a pair of cantilevered structures connected to the RF conductor; a plurality of air bridges connected to the pair of cantilevered piezoelectric actuators; and a plurality of contact dimples on the contact pad. Preferably, the RF transmission line comprises a pair of co-planar waveguide ground planes flanking the RF conductor; and a plurality of ground straps connected to the pair of co-planar waveguide ground planes, wherein the RF transmission line is operable to provide a path along which RF signals propagate.
