There are two varieties of flip top actuators: front flip and back side flip. As the names imply, the actuator on the front flip style flips from the front of the connector while the back side flip has the actuator rotating toward the back of the connector. Back side flip connectors are the more popular, especially for applications where the cable may be routed upward from the connector. This would pose the possibility of disengaging the actuator on a front flip connector, allowing the cable to be released.
