An electrical connector system includes a receptacle connector having a housing, a contact assembly held in the housing and an insert movably received in the housing and supporting the contact assembly. The housing has a cavity and a mating end including a slot receiving a circuit card. The contact assembly is received in the cavity and includes contacts. Each contact has a base fixed in the cavity and a mating end movable relative to the base between an undeflected position and a deflected position. The insert is received in the cavity and is movable in the cavity between a forward position and a retracted position. The insert holds the mating ends of the contacts in the undeflected positions when in the forward position. The insert engages the contacts and forces the contacts to the deflected positions when in the retracted position.
