Abstract:
1. A relay, comprising: first and second contacts, said contacts being selectively connectable for closing an electric circuit; a coil wound around the contacts along a longitudinal axis to generate a magnetic field that connects the contacts in one of an energized or de-energized state and disconnects the contacts in the other of the energized or de-energized state; a first electrically conductive shield provided adjacent to a first end of the relay and electrically connected to the first contact, the first electrically conductive shield extending at least partially around a switching element supporting the first contact; a second electrically conductive shield, the second electrically conductive shield being electrically connected to the second contact and extending at least partially around a switching element supporting the second contact, wherein the second electrically conductive shield is substantially coaxial with the first electrically conductive shield and separated a distance apart from the first electrically conductive shield along the longitudinal axis; a plurality of surface mountable pads, each electrically connected to a separate one of the first contact, the second contact and opposite ends of the coil for surface mounting the relay to a printed circuit board without penetrating the printed circuit board; and wherein the distance separating the first shield from the second shield forms an air gap across which the first and second electrically conductive shields do not overlap and are not electrically connected across said air gap.
