作为优选实施方式，如图2-3所示，本发明的上述铁路信号继电器还包括防护片4，防护片4设在磁体3与衔铁1接触的一面，且不把磁体完全包覆，图中所示，磁体3为圆形，防护片4仅遮挡磁体3的中间部位，磁体3的上部和下部还裸露在空气中，防护片4的两端分别与轭铁2固定连接，具体为：防护片4的两端开设通孔，轭铁2在对应通孔的位置开设盲孔，采用螺钉将对应的通孔和盲孔螺纹连接；
当继电器处于释放状态时，磁体3通过防护片4间接和衔铁1与轭铁2接触一侧的壁面吸合，可以避免磁体3与衔铁1直接接触，造成磁体3损坏；
作为优选的，防护片4采用弹性防护片，具体可以选取锡青铜片，锡青铜片具备较好的弹性，可以在继电器处于释放状态时，对继电器衔铁释放产生的冲击力起到一定的阻尼的作用，如果采用一个弹性较小的零件，继电器衔铁释放后会产生衔铁1与防护片4之间“硬碰硬”的状态，碰撞产生的冲击力可能会造成衔铁1的弹跳，进而反馈到接点上，造成接点的弹跳。
作为优选实施方式，释放位置保持组件还包括推杆5(如图4所示)和弹力支撑片6，弹力支撑片6在继电器上设置时，会朝向衔铁1掰设一定角度；
推杆5一端和衔铁1与轭铁2接触的一端通过连接件连接，连接件包括连接板，螺栓和螺母，连接板包括连接底板，连接底板的两个对侧分别沿垂直于连接底板的同侧方向，一体成型延伸连接板一和延伸连接板二，延伸连接板一和延伸连接板二上分别开设通孔，推杆5与衔铁1连接端开设通孔，衔铁1与推杆5连接端开设通孔，螺栓依次穿过各个通孔，然后与螺母螺纹连接，将推杆5一端与衔铁1与轭铁2接触的一端固定连接；
推杆5另一端与弹力支撑片6接触，具体为推杆5另一端开设限位钩，弹力支撑片6的上端置于推杆5内的限位钩内，对推杆5另一端进行限位以及支撑，且在继电器处于释放状态时，弹力支撑片6对推杆5另一端进行支撑后，弹力支撑片6朝向衔铁1的掰设角度会变小，由于弹力支撑片6的弹性恢复性能，会对推杆5有一个反向压力；
在上述释放位置保持组件包括磁体3的基础上，再结合推杆5和弹力支撑片6，一方面，可以增强继电器在释放位置时的释放位置保持力，另一方面，由于弹力支撑片6的反向压力就是一个反向弹力，基于反向弹力的可调节性，可以对继电器在释放位置时 的释放位置保持力进行调节；
图中示意限位钩的数目为两个，分别在推杆5的另一端的两侧对称设置，这样设置的话，可以在继电器上设置两个弹力支撑片6，当然图中限位钩的数目仅为示意，本领域技术人员可以根据实际需要设定。
作为优选实施方式，上述铁路信号继电器还包括第一接点组件和第二接点组件；第一接点组件用于与外部高压电路连接，第二接点组件用于与外部低压电路连接；
第一接点组件包括第一动断接点7，第一动接点8和第一动合接点9，当继电器处于释放位置时，第一动接点8与所述第一动断接点7闭合，第一动接点8与第一动合接点9分离，当继电器处于吸合位置时，第一动接点8与第一动合接点9闭合，第一动接点8与第一动断接点7分离。

通过设置上述两组接点，分别与外部高压电路连接或与外部低压电路连接，可以使得继电器适用电路不单一，能适用于外部低压或高压电路，提高继电器的适用范围。
作为优选实施方式，上述铁路信号继电器还包括第一限位组件，第一限位组件包括第一限位杆13和第二限位杆14；

通过将上述第一动接点8限定在第一限位杆13和第二限位杆14之间的限位行程内， 从而保证第一动接点8可以准确的与第一动断接点7闭合或与第一动合接点9闭合。
并且，第一限位杆13和第二限位杆14与第一动接点8接触一侧设定为弧形边，避免第一动接点8在与第一限位杆13和第二限位杆14接触过程中受到损伤。
图中示意第一限位组件采用两组，在推杆5的一端进行设置，具体是在推杆5一端的两侧壁对称设置，这样的话，对应可以在继电器上设置两组上述的第一接点组件，从而可以增设外接高压电路；当然本发明的继电器的第一限位组件的数目不仅限于两组，本领域技术人员可以根据实际需要进行设定。
作为优选实施方式，上述铁路信号继电器还包括第二限位组件，第二限位组件包括第三限位杆15和第四限位杆16；

通过将上述第二动接点11限定在第三限位杆15和第四限位16杆之间的限位行程内，从而保证第二动接点11可以准确的与第二动断接点10闭合或与第二动合接点12闭合。
并且，第三限位杆15和第四限位杆16与第二动接点11接触一侧设定为弧形边，避免第二动接点11在与第三限位杆15和第四限位杆16接触过程中受到损伤。
图中示意第二限位组件为两组，在推杆5设置第一限位组件一端的对应端进行设置，具体是在推杆5的两侧壁对称设置，这样的话，可以在继电器上设置两组上述的第二接点组件，从而可以增设外接低压电路。
作为优选实施方式，如图5所示，上述铁路信号继电器还包括电弧隔板17，可以对第一动接触头与第一动断接点7或第一动合接点9闭合过程中或第二动接触头与第二动 断接点10或第二动合接点12闭合的过程中产生的电弧进行隔档，提高继电器的使用安全性能；
