A charging device for electric vehicles or plug-in hybrids has a housing. At least one printed circuit board with fuses thereon is arranged on the printed circuit board. The printed circuit board, together with the fuses, is arranged in the interior of the housing and is connected to the housing in a force-fitting and/or interlocking manner by at least one fastening element (2). A covering element (1) covers the printed circuit board and the fastening element (2) at least in sections, and insertion or removal of the fuses onto or from the printed circuit board can be carried out only by removing the printed circuit board from the interior of the housing. The covering element (1) has to be damaged at least in sections to remove the printed circuit board.

A short-circuit shutdown switch is disclosed having a load current path and a cutting plunger. The load current path has a separating member with a first predetermined cutting zone, a second predetermined cutting zone, and a central section positioned between the first predetermined cutting zone and the second predetermined cutting zone. The cutting plunger is positioned to cut the first predetermined cutting zone and the second predetermined cutting zone.

The invention relates to a protective collar for at least partially receiving an actuating element which extends through a housing of a control unit and projects beyond an outer side of the housing. The protective collar has a base with a through-opening and a first circumferential collar radially spaced from the through-opening and extending from an upper surface of the base in a first direction. The first collar has at least two cut-outs such that the first collar forms at least two wings, wherein at least one of the wings has at least one predetermined breaking point extending in the circumferential direction.

A physical barrier breach sensor is disclosed that contains a frangible material that, upon displacement, opens a microswitch that de-energizes power or stops the flow of electricity to an electrical device. Displacement of the frangible material causes activation of the sensor, such as due to a vehicle colliding with a streetlight pole containing the sensor. The device is omnidirectional, operating regardless of direction of impact from the vehicle or activation, and has the ability to disconnect power when, for example, a streetlight pole or other structure (e.g., a parking gate) falls or breaks due to a shearing impact (such as a vehicle collision) or due to tension created by wind or weight failure.
