这种联锁由一根随道岔尖轨动作的转辙杆和一根随信号机导线动作的信号杆组成

这种联锁由一根随道岔尖轨动作的转辙杆和一根随信号机导线动作的信号杆组成。杆上刻有缺口，通过转辙杆和信号杆相互位置的变化，来模拟道岔和信号机的不同状态，实现道岔和信号机之间的联锁。这种联锁只有道岔开通位置符合进路要求时，转辙杆缺口位置才不阻碍信号杆移动，信号机才能受到导线传递来的拉力开放，否则，转辙杆将阻止信号杆移动，信号机也就不能开放。信号机一旦开放之后，信号杆所处的位置，将反过来阻止转辙杆再变位，即将道岔锁闭在固定的位置上。
这种联锁设备只适用于一根导线操纵的单线臂板信号机。由于导线控制距离短，受气温变化的影响大，经常需要人工检查和调整，而且进路的空闲是依靠铁路规章来人为保障的。因此，这种联锁一般用于运量小、股道短和道岔数少的无电源设备的车站。

signal by a switch rod of the interlocking rod with the switch action and a wire with signal action composition. Rod inscribes the gap through the switch lever and the signal rod position changes, to simulate the different states of the switches and signals, realize the interlock between the switch and the signal machine. The interlocking turnout only opened position in line with the requirements of the route and switch lever gap position don't hinder the signal rod to move, the signal can be by wire transfer to pull open. Otherwise, switch bar will stop signal rod to move, the signal also cannot open. Once the signal machine is open, the position of the signal rod is located,In turn will prevent the switch lever to change position, to switch locking in a fixed position. This interlocking device is only suitable for a single wire arm control of the single arm plate signal machine. Due to the short distance of the wire control, the impact of temperature changes, often need manual inspection and adjustment, and the way of the idle is to rely on the railway regulations to protect the people. Therefore, this is generally used for small volume, interlocking and short track turnout of less number of no power station equipment.
