Abstract (en)

The actuator has switching magnets (3,4) on either side of an oscillating driven armature (2) in a multiple part carrier arrangement (5). The switching magnets have coil cores (6,7) with apertures for magnetic coils (9,10). The coil cores are arranged in the carrier arrangement between separate auxiliary supporting carriers (11,11') with their inner sides in flat contact with a heat conducting stop. The coils, which are only partly within the cores, are externally closed by sections outside the supporting carriers.
