Relay for ultra high frequency coaxial switching

A relay for switching high frequency lines comprising, a support, a plurality of spaced apart coaxial contacts on said support, said coaxial contacts comprising a first coaxial contact between a second coaxial contact and a third coaxial contact, first and second rigid blade contacts, a ground plane spaced from said coaxial contacts, a force transmitting insulating pusher fixed to each rigid blade contact, and means for alternately moving said blade contacts from a one position in which said first blade contact engages said first and second coaxial contacts and said second blade contact engages said ground plane, to another position in which said second blade contact engages said first and third coaxial contacts and said first blade contact engages said ground plane, said means comprising a leaf spring connected at its center to a central support, means for connecting said pusher element for said first blade contact to said spring on one side of said central support, means for connecting the pusher for said second blade contact to said leaf spring on the other side of said central support, an armature pivotable about a central axis, said armature having first and second arms projecting in opposite directions from said axis, means at one end of said armature for engaging one end of said spring, means at the other end of the armature for engaging the other end of said spring, said engaging means being alternately movable with the armature, to a first position in which one of the engaging means engages one end of the leaf spring and deflects the spring to move said first blade contact into engagement with said first and third coaxial contacts, and in which the other engaging means is spaced from the other end of the spring to permit the spring to move the second blade contact into engagement with the ground plane, and to a second position in which the other engaging means engages the other end of the leaf spring and deflects the spring to move the second blade contact into engagement with the second and third coaxial contacts, and in which said one of the engaging means is spaced from the other end of the spring to permit the spring to move the first blade contact into engagement with the ground plane, and electromagnetic means for pivoting said armature.
