A passenger control unit 206 is provided that may include a push-button 220, power assembly 404, and control and communication circuitry 406. The push-button may be for control of a passenger service unit (PSU) 208 onboard a passenger vehicle, and may also generate mechanical energy when pushed. The power assembly may convert the mechanical energy to electrical energy, and store the electrical energy, solely from which the control and communication circuitry may be powered. The control and communication circuitry may include a microprocessor 408 and a communications interface 410. The microprocessor may receive an indication when the push-button is pushed, and generate an instruction to control the PSU in response thereto. And the communications interface wirelessly transmit the instruction to a control unit configured to effect control of the PSU based thereon. |
