An apparatus for controlling the connection of an electrical module to an electrical receptacle. The module is provided with a power switch having a movable switch activator for inhibiting a flow of current to the electrical module when the switch activator is in a first position and for flowing a current to the electrical module when the switch activator is in a second position. The switch activator has a side portion which extends from a surface of the module when the switch activator is in the second position, but which does not extend from the surface of the module when the switch activator is in the first position. A lock member is disposed on a surface of the module and is slidable to a retracted position when the switch activator is in the first position. The lock member extends from the module and abuts against the side portion of the switch activator when the switch activator is in the second position. When the lock member is in the retracted position, the module may be readily connected to or disconnected from the receptacle. When the lock member is extended, the module is prevented from being positioned in the prescribed orientation for connecting to the electrical receptacle, or, when the module and receptacle are already connected, the lock member extends into a bounded opening in the surface of the receptacle and the module cannot be disconnected from the receptacle. |
