Power control apparatus

A power control apparatus comprising:

• a rotating terminal including a circumferential outer peripheral surface, and having electrically conductive areas and non-electrically conductive areas alternately arranged on the outer peripheral surface in a circumferential direction thereof;
• and
• a pair of fixed terminals fixed and disposed outwardly of a path of rotation of the outer peripheral surface,
• wherein the pair of fixed terminals is switched between an electrically conducting condition in which the pair of fixed terminals are electrically connected together through the rotating terminal, and an interrupting condition in which the electrical connection between the pair of fixed terminals through the rotating terminal is interrupted in accordance with a rotating position of the rotating terminal,
• wherein an electrically-conductive contact spring is provided at the outer peripheral surface of the rotating terminal, and the contact spring is fixed at one end thereof to the outer peripheral surface while the other end thereof serving as a free end projects from the outer peripheral surface, and
• each of the pair of fixed terminal includes a contact surface in which the contact spring is brought into contact with the contact surface in a resiliently-deformed condition.
