A control module adapted to be attached to a power adapter is described. The control module comprises a plurality of contact elements including a first contact element adapted to receive a line voltage and a second contact element adapted to receive a reference voltage; a first actuator extending from a housing of the control module and adapted to engage with a connector of a power adapter; a second actuator extending from the housing of the control module and adapted to engage with a tamper resistance element of a power adapter; a control circuit adapted to generate a signal; and a third contact element coupled to the control circuit; wherein the control circuit generates to the signal adapted to be routed to the power adapter by way of the third contact element to detect a change in a state of a switch of a power adapter.
