1. A hand-held treatment system, comprising:
a hand-held treatment device and at least one attachment,
wherein the treatment device has a movable treatment part and an electric drive motor system for moving the treatment part, wherein the electric drive motor system has at least one electrical path with at least one interruption,
wherein the at least one attachment has a contact bridge with a jumper,
wherein the treatment device and the at least one attachment are configured for spatial arrangement of the at least one attachment from a hazard position into a safety position, which is different from the hazard position, on the treatment device in such a manner that:
when the at least one attachment is in the hazard position, the at least one contact bridge does not electrically bridge the at least one interruption,
when the arrangement of the at least one attachment is in the safety position, the at least one contact bridge electrically bridges the at least one interruption via the jumper,
wherein the electric drive motor system has at least one contact piece and/or a series-connected contact piece, and
wherein the contact piece and/or the series-connected contact piece are/is configured to contact the at least one contact bridge and are/is mounted in a floating manner, relative to a housing of the hand-held treatment device.
