<p>A railway switch circuit controller (100) has a housing (102) enclosing a laterally movable platform (216) with a first and second target (228, 230) affixed thereupon. A first and second proximity sensor (220, 222) within the housing (102) is positioned to detect the first and second target (228, 230), respectively, such that the proximity sensor (220, 222) upon detection of the respective target (228, 230) may provide a signal. The platform (216) is connected to a point detector connecting rod (120) of a railway switch, thereby to be movable relative to the point detector connecting rod (120).</p> |
