Abstract: The invention relates to a Switch connector for mounting on a printed circuit board, adapted to receive a mating connector in an insertion direction along an insertion axis. The switch connector comprises a shield, a contact element, and a contact spring having at least one fixed leg, at least one elastically deflectable switching leg, and at least one spring bend, the fixed leg and the switching leg extending from the spring bend in a common direction and passing the insertion axis. The switching leg is adapted to be moved by insertion of the mating connector from a rest position, at which the switching leg exerts a spring force onto the contact element, to a switching position, at which the switching leg is spaced apart from the contact element, at least one spring force flux that in the rest position is generated by the switching leg and guided in a closed loop to the fixed leg. To increase the reliability of the switching function, the shield is arranged in the closed loop of the spring force flux.
