Abstract: Means for coupling together two assemblies wherein the first assembly has an end wall formed by a first apertured plate, and the second assembly includes an end wall to which is secured a rotatable end plate. The rotatable end plate carries clamping means which can engage and clamp to apertures in the first apertured plate of the first assembly, whereby the two assemblies are coupled together. In using the apparatus, the two assemblies are positioned adjacent to each other with the rotatable plate and first apertured plate in alignment and the clamping means on the rotatable plate engaging apertures in the first apertured plate. Rotation of the rotatable plate then locks the assemblies together.

Abstract: Coupling apparatus comprising two plates to be coupled together, with each plate carrying a locking mechanism for receiving a coupling member, the coupling member having two ends, each end being adapted to engage and couple to the locking mechanism on one of the plates whereby the two plates can be rigidly coupled together. Each plate carries two flexible locking tabs which are offset from each other, and the coupling member carries two holes which are offset from each other and each of which is adapted to receive one locking tab of each plate.

Abstract: A low profile reed keyswitch which includes a magnetically actuated reed switch. The reed switch is mounted parallel to the keyswitch base on a retaining fixture which resistively holds the body of the reed switch. The leads of the reed switch freely pass through the base where they are available for direct connection to an external circuit. A permanent magnet is carried in a plunger which is spring biased away from the reed switch. The reed switch is actuated when an operator depresses the plunger to move the magnet toward the reed switch.
