Closing device with electrical contacts

A closing device comprising:

• a first closing part which has a housing and a blocking piece disposed on the housing;
• a second closing part which has a sprung locking element which at least in portions is configured so as to be spring-elastic;
• and
• magnetic means which act between the blocking piece of the first closing part and the second closing part and cause a magnetic attraction force between the blocking piece of the first closing part and the second closing part,
• wherein
• the first closing part for closing the closing device is capable of being placed on the second closing part in a closing direction;
• wherein the blocking piece and the sprung locking element in a closing position are mutually engaged such that the first closing part in the direction counter to the closing direction is locked in relation to the second closing part;
• wherein the sprung locking element for releasing the closing device is displaceable relative to the blocking piece in an opening direction that is substantially transverse to the closing direction, so as to disengage the sprung locking element and the blocking piece,
• wherein the blocking piece is disposed so as to be movable on the housing of the first closing part such a manner that said blocking piece in a retracted position is at least in part enclosed in a receptacle chamber of the housing, and in a deployed position projects from the housing in such a manner that said blocking piece can be brought to engage with the sprung locking element, and
• wherein
• at least one first electrical contact element is disposed on the blocking piece and/or the housing, and at least one second electrical contact element is disposed on the second closing part.
