    • An optoelectronic switch position detection apparatus for detecting the switch positions of a switch element movable in switch position steps in a switch direction with each switch position step corresponding to a switch position includes receivers, a light, and a shutter. The receivers are arranged at a distance correspondingly from each other of a switch position step in the switch direction of the switch element. The shutter is coupled to the movement of the switch element to move relative to the receivers and the light as the switch element moves in the switch direction between switch positions. The state of one of the receivers changes between an exposed state in which the receiver is exposed to the light and a shaded state in which the shutter shades the receiver from the light when the switch element moves in the switch direction from one switch position to an adjacent switch position.
    • 一种光电开关位置检测装置,用于检测在开关位置上可移动的开关位置的开关位置,其中每个开关位置步骤对应于开关位置包括接收器,光和快门。 接收器相对于开关元件的开关方向上的开关位置台阶彼此相对设置。 当开关元件在开关位置之间的开关方向上移动时,快门耦合到开关元件的移动,以相对于接收器和光线移动。 一个接收器的状态在接收器暴露于光的曝光状态和遮光状态之间变化,其中当开关元件沿开关方向从一个开关位置移动到 相邻开关位置。
