摘要:
Provided is a relay that includes first and second contacts that are selectively connectable for closing an electric circuit. A coil wound around the contacts along a longitudinal axis can 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 is provided adjacent to a first end of the relay and electrically connected to the first contact, and a second electrically conductive shield, the second electrically conductive shield being electrically connected to the second contact. The first electrically conductive shield extends at least partially around the first contact and the second electrically conductive shield extends at least partially around the second contact. 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.
