ABSTRACT:
The device comprises, for each selector element, a high-speed electromagnet having a fixed core with a single coil, and an armature consisting of a lightweight blade. When the coil is energized, the blade is moved into one position, and is restored to another position by means of a compression spring when the coil is de-energized, with a response time of less than 4 ms. The electromagnets are housed in the support of a selection assembly, and packed in at least two offset rows. Each coil is energized at a first voltage and is subsequently maintained energized at a lower voltage.
