An electromechanical circuit uses a plunger to open and close a circuit as an indication of the position of a flip portion of a mobile communication device. The plunger includes an electrically conductive portion which slidingly contacts a contact pad. Upon contacting the contact pad, a change in logic states occurs which triggers circuitry to activate or de-activate the internal electronics within the communication device. This allows a user, for example, to activate a phone to receive a call without having to depress a specified switch. A common cam-follower mechanical configuration is used to cause the plunger to translate axially as the flip portion is moved.
