Abstract
A housing made of insulating material has a plurality of slots each accommodating a contact spring including a pair of legs. The free ends of each leg are formed as contact noses facing each other. The contact noses define an opening through which an edge of a printed circuit board may be inserted with the board held at an angle with respect to its final position. The printed circuit board is then rotated about an axis parallel to the edge into its final position in which it is locked by a pair of resilient detent tongues formed at the ends of the housing. In this final position, conductor strips provided at the inserted edge of the printed circuit board make electrical contact with the noses of the contact springs. During rotation of the circuit board, minute sliding movements occur at the contact locations providing a cleaning effect on the contacts without causing excessive wear thereof.
