  • Dual shielded relay reed pack
    Patent number: 5559482
    Abstract: A reed relay is provided with two shields. The shields are fabricated from copper foil and insulated from each other by polyester tape or film. One shield is connected to one lead of a switching element and the other shield is connected to another lead of a switching element. The shields are wrapped around the switching element in an overlapping manner. The dual shield configuration reduces leakage and interference to improve performance, particularly in low current applications.
