Abstract
The switch includes an annular permanent magnet, a plate of soft magnetic material at one side of the magnet, a stationary electric coil at the opposite side of the magnet, and an unrestrained free-flying member of soft magnetic material coaxial with magnet and coil and movable axially in them toward and away from the plate. It normally is held by keeper means in a rest position away from the plate, but means are provided movable relative to it for first engaging and then pushing it toward the plate until the magnetic attraction between the magnet and the free-flying member causes that member to fly from the pushing means to the plate at high velocity. This creates a rapid change in flux in the free-flying member and produces a voltage pulse in the coil.
