Connector assemblies, switchable housings and high density panels are disclosed, wherein the connector assemblies include multiple cable assembly connectors and switchable housings. A switchable housing includes one or more release members configured to contact the latching portion and provide a compressing force sufficient to selectively disengage the cable assembly connector from the mating connector and a pull tab assembly in contact with the release members and configured to move along a coupling shaft. Movement of the pull tab assembly in a second direction along the coupling shaft may cause the pull tab assembly to compress the release members, thereby causing the release members to provide the compressing force to disengage the cable assembly connector from the mating connector.
