| 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.

| An electromagnetic device including a plural number of individual magnetic circuits, each with magnetically operable armatures, assembled in a unit. Each magnetic circuit includes a first coil and two stationary yokes disposed on opposite sides of the coil with an armature extending through the coil and pivoted at one of its ends. (Two armature pivot structures are disclosed.) The other end of the armature is disposed for operating movement between two stationary pole faces, one on each of the two yokes. A second, ''''extra'''' coil is disposed around a portion of one of the two yokes for each magnetic circuit. By appropriate energizing of the two coils, selected disposition of the armature can be maintained and attained. The armatures can be used for various purposes, e.g., to operate mechanical devices, or as a relay operator to actuate one or more contact spring sets. The device is assembled in a manner to enable independent operation of the armature of each magnetic circuit without the magnetic circuit affecting the positions of the other armatures in the assembly.

| Four permanent magnets are disposed at predetermined angular intervals equal to an angle of 36* on a circular magnetic substrate by having the S pole faces of the first and fourth magnets and the N pole faces of the second and third magnets fixed to the substrate on a circle concentric to it. With the substrate rotated, a reed switch above it faces successively the first and second magnets to close the switch, the second and third magnets to open the switch, and the third and fourth magnets to again close the switch to permit pulses to be generated.
