  • Patent number: 5177459
    Abstract: A relay having a contact and terminal base assembly having a platform with mounting holes formed in corners thereof, to receive depending limbs which extend from the coil and plunger assembly so that, in this way, the two assemblies are mechanically engaged by a socket-type connection. Each assembly, then, may be separately manufactured, to support the contacts and terminals in the one assembly, and to support the coil and plunger in the other assembly, respectively; then, the two are socketed together, to form the complete relay. Such modular construction simplifies manufacturing, and facilitates final, factory adjustments, of each module-assembly, before the two are mechanically joined.

  • Patent number: 4376895
    Abstract: An electromechanical switching device has a housing containing an armature. This armature is mounted in the housing to reciprocate between a closed and an open position. A coil mounted near the armature in the housing can magnetically hold the armature in its closed position. A manually operable member is mounted in the housing to reciprocate between a set and a reset position. This member can be moved into the set and reset positions to drive the armature toward its closed and open positions, respectively. Being arranged in this fashion the coil can be operated by a relatively small current. This current may be insufficient to attract the armature from its open to its closed position. However, the full travel of the armature is accomplished by the combined effects of the manually operable member and the coil.
