<p>A rotating terminal (16) has a circumferential outer peripheral surface (21a, 24a) having its center disposed at an axis (13, 21b) of rotation of the rotating terminal, and has electrically conductive areas and non-electrically conductive areas alternately arranged on the outer peripheral surface in the circumferential direction. At least one pair of fixed terminals (17, 18) are fixed and disposed outwardly of a path of rotation of the outer peripheral surface of the rotating terminal. In accordance with a rotating position of the rotating terminal, the pair of fixed terminals can be 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 pair of fixed terminals are not electrically connected together through the rotating terminal. <IMAGE></p> |
