Abstract: An electrical module assembly is provided that is configured for latching engagement with a receptacle assembly. The module assembly comprises a module housing having an exterior envelope and an interior cavity. The exterior envelope of the module housing is configured to be plugged into the receptacle assembly. A release mechanism is joined to the module housing. The release mechanism is moveable between locked and unlocked positions. The release mechanism is configured to unlock the module housing from the receptacle assembly when the release mechanism is moved from the locked position to the unlocked position. A detection switch is located within the interior cavity of the module housing. The detection switch monitors a position of the release mechanism and provides latched and unlatched state signals based on the position of the release mechanism. The latched state signal indicates that the module housing is locked in the receptacle assembly.
