Coat Hook Switch

The coat hook mounted on the office wall appears ordinary until pressed in a specific sequence, revealing its true function as a disguised lift release mechanism. Its brass-plated surface shows deliberate wear patterns where fingers apply pressure, and the surrounding air vents betray controlled ventilation currents that mask its mechanical operation. Grover, distracted by the arrival of his car, remains unaware of the hidden function embedded in this mundane fixture.
