A method and system for powering at least one switch provided on the steering wheel assembly of an off road vehicle. The method or system includes providing a rechargeable accumulator in the steering wheel assembly and powering the switch from the accumulator. The method or system also includes an energy source for recharging the accumulator along with the step of comparing a detected energy level and/or a detected time elapsed to a threshold value corresponding to the energy level being sufficient to power the switch and enable its use. Said aforementioned step is utilized to determine if there is energy sufficiency or an energy insufficiency in the accumulator. If the comparison yields an energy insufficiency, the energy source may be instructed to recharge the accumulator, and hence increase its energy level. The above discussed steps may be repeated to ensure the sufficiency of the energy level to power the switch.
