Lamp holder and lamp socket and system with lamp holder and lamp socket and method for supporting a lamp socket in a lamp holder

A lamp socket including socket contacts for electrically contacting lamp holder contacts, the lamp socket comprising:

• a mounting dome that is insertable into a lamp holder and includes a support pin that is linked in a spring elastic manner so that the support pin mechanically anchors the lamp socket in the lamp holder,
• wherein the mounting dome includes support surfaces which define a movement path along which the support pin is moveable,
• wherein the movement path displaces the support pin from an idle position in a first direction through a displacement section of the movement path while building up a spring load during a relative movement of the lamp socket and the lamp holder,
• wherein the movement path returns the support pin through a return section of the movement path towards an idle position of the support pin partially reducing the spring load during a relative movement of the lamp socket and the lamp holder, and
• wherein the movement path maintains the support pin in an arresting position which forms a portion of the return section of the movement path while maintaining a residual spring load during a relative movement of the lamp socket and the lamp holder.
