Abstract
A switch pack for a vehicle and systems comprising the same. One system includes the switch pack and a control unit mechanically coupled to the vehicle. The control unit includes a first antenna coil electrically coupled to an electrical system of the vehicle. The first antenna coil receives a current from the electrical system and produces a magnetic field. The switch pack includes a second antenna coil, at least one user-actuated device, and a wireless transmitter electrically coupled to the second antenna coil. The second antenna coil is positioned within the magnetic field and receives an induced current from the magnetic field. The wireless transmitter receives the induced electrical current from the second antenna, uses the induced electrical current to determine a state of the at least one user-actuated device, and uses the induced electrical current to wirelessly transmit the state of the at least one user-actuated device.
