Abstract: A miniaturized electromagnetic interposer assembly is described capable of high speed operation from electronic trigger pulses and having coil-interposer arrays of dimensions suitable for direct positioning alongside a set of standard paper tape punches stacked in parallel groups for ten punch positions per inch. An interposer member electromagnetically moved between two stable positions includes a semiflexible twisted leaf spring stiff in the direction of movement of an electromagnetically moved member and flexible in the direction of movement of punches in their cutting stroke. The interposers and a punch drive comb assembly attain side by side positions in a notch cut into the side of a punch pin shaft.
