[0002] Rail transit switch equipment is used to change the direction of turnout opening, lock the movable part of the turnout, and perform real-time detection and indication of the position status of the turnout. The switch machine usually uses an external locking device to drive and lock the movable part of the turnout, and uses the detection rod of the close contact checker (commonly called the indicating rod in China) to reflect the position of the turnout point rail or heart rail. The close contact checker detects the status of the external locking device and the position of the detection rod to determine the locking and close contact status of the turnout, and controls the connection or disconnection of the electrical switch according to the detection results to indicate the status and position information of the turnout to the turnout control system. Usually, the switch machine has two terminal positions: the action rod is pulled in and extended, corresponding to the turnout positioning close contact locking and the reverse close contact locking respectively.
