ABSTRACT:
The invention relates to an overload protection device (1) comprising a housing (2) which is designed to be fixed to a manipulation device. The overload protection device comprises a tool holder (3) for fixing a tool that is attached to the housing in a displaceable manner, a pre-tensioning unit (4) for generating a pre-tensioning force between the housing and the tool holder, the pre-tensioning unit being configured as a piston assembly with a pressure piston which can be loaded by a medium and with a switching unit (5) that operates by means of relative displacement between the housing and the tool holder. The switching unit has a least one electrically conducting switching surface (6) and at least one electrically conducting contact element (7) that can be brought into electrical contact with the switching surface, the switching surface (6) and the contact element (7) being provided on an opposing surface section (8) of the tool holder and the housing. The contact element (7) is configured as a sealing element, which seals off at least sections of the pressure piston from the switching surface (6).
