摘要： A cover sheet is placed over the crosspoint relays within a crosspoint matrix. The cover sheet has a particular design which completely covers the crosspoints near the center of the matrix and only partially covers the crosspoints near the edges of the matrix. The crosspoints at the corners are not covered at all. The differences in the pickup and dropout values between the center, edge, and corner crosspoints is thereby eliminated.

摘要： A sealed contact for use in electromechanical relays has a flat base plate consisting of an annular outer member and a discshaped inner member joined together by means of a glass seal. A hood-shaped cover containing an armature holding spring and attached armature is sealed to the outer member of the base. The uniformly flat base and cover allow the contact to be used in a wide variety of electromechanical relays.
