1. A system for a vehicle, the system comprising:
a control unit mechanically coupled to the vehicle, the control unit including
a first antenna coil electrically coupled to an electrical system of the vehicle, the first antenna coil receiving a current from the electrical system and producing a magnetic field; and
a switch pack, the switch pack including
a second antenna coil positioned within the magnetic field and receiving an induced electrical current from the magnetic field,
at least one user-actuated device, and
a wireless transmitter electrically coupled to the second antenna coil, the wireless transmitter configured to
receive the induced electrical current from the second antenna coil,
use the induced electrical current to determine a state of the at least one user-actuated device, the state of the at least one user-actuated device including one of a plurality of states including at least a first state and a second state, and
use the induced electrical current to wirelessly transmit the state of the at least one user-actuated device, the wireless transmitter transmitting a first signal in response to the user-actuated device being in the first state and transmitting a second signal in response to the user-actuated device being in the second state.
