A connector assembly for connecting a rigid circuit board to a flat flexible circuit. The connector includes a U-shaped contact element, U-shaped compression spring and U-shaped housing. The housing is dimensioned to receive the circuit board at an edge thereof and includes a receptacle for the flexible circuit. The contact element is mounted in the housing and is in contact with a contact surface of the circuit board and a contact surface of the flexible circuit. The housing includes openings through which a respective contact arm of the contact element extends to contact the circuit board. The compression spring includes pressing surfaces which exert a pressing force against the flexible circuit to effect contact between the flexible circuit and the contact element.
