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.
