An assembly has a handle, a brush holder, and a support that connect and disconnect to each other using a locking mechanism. The handle reversibly connects and disconnects from the brush holder. The locking mechanism includes a connecting member on the brush holder that attaches to the handle by interaction of a locking flange on the connecting member with a pair of teeth inside of the handle. Insertion of the support within the brush holder extends a post on the support through the connecting member to interact with the handle and enable disconnection of the handle from the brush holder when the support is fully engaged by the brush holder. The locking mechanism prevents the handle from releasing from the brush holder before the brush holder is completely seated on the support.

A method for making contact wires for sliprings comprising the steps of: coating and/or plating a wire with a first metal of the group of nickel, chrome or a combination thereof; coating and/or plating the wire with a second metal of the group of gold, silver, or a combination thereof; delivering laser radiation and generating an interference pattern of the laser radiation to the surface of the wire; heating the surface selectively as defined by the interference pattern, modifying of the crystal structure and/or providing protrusions and/or recesses due to melting and/or evaporation of the surface material.

The invention relates to the use of a carbon composite material for manufacturing electrical contact elements of a fuel pump operated in a fuel environment, the contact elements being designed as carbon molds, wherein, in addition to carbon, the carbon composite material comprises a thermosetting or thermoplastic binder and a metal content that amounts to more than 0.5% and less than 25% of the total mass of the carbon composite material.

A slipring brush includes a body of a metal wire or metal band having a contact area for contacting a slipring module. The contact area is selectively coated by a contact material like gold or silver or an alloy thereof. The body preferably includes Copper, Nickel, Iron, or an alloy thereof. Coating may be done by electroplating, physical vapor deposition (PVD) or chemical vapor deposition (CVD).
