Abstract

A triggering unit includes a tappet having a moving bearing, a power accumulator, a holding device and a printed circuit board coil. In the normal state the power accumulator acts upon the tappet with a power accumulator force in the direction of the first stop position and the holding device holds the tappet with a holding force in the second stop position. A printed circuit board coil force can be generated by an activation of the printed circuit board coil. The power accumulator, the holding device and the printed circuit board coil are formed such that the tappet rests in the second stop position in the inactive state of the printed circuit board coil and through an activation of the printed circuit board coil, the tappet assumes the first stop position such that the triggered status is given.
