To improve the reliability of a train emergency stop switch.SOLUTION: A train emergency stop switch 10 includes: a casing; an emergency stop button 40 for starting alarming; a reset button 42 for canceling the alarming; a holding mechanism 50 for mechanically holding an alarming state and a monitoring state; and alarming means 80 for carrying out alarming in the alarming state and stopping the alarming in the monitoring state. Thus, each state can be reliably held by mechanically holding the alarming state and the monitoring state even when an electric failure such as an instantaneous blackout occurs. Thus, reliability can be improved by preventing an erroneous operation of the train emergency stop switch 10. In addition, as both the emergency stop button 40 and the reset button 42 are positioned so as to be operable from the front side of the casing 12, both the buttons can be operated without any problem even when the train emergency stop switch 10 is embedded in the pillar of a platform.SELECTED DRAWING: Figure 2

    【課題】列車非常停止スイッチの信頼性を高める。【解決手段】列車非常停止スイッチ10は、筐体と、発報を開始するための非常停止ボタン40と、発報を解除するための復帰ボタン42と、発報状態及び監視状態を機械的に保持する保持機構50と、発報状態のときに発報を行い、監視状態のときに発報を停止する発報手段80とを含んでいる。このように、発報状態及び監視状態を機械的に保持することで、瞬時停電等の電気的な障害が発生しても、各状態を確実に保持することができる。これにより、列車非常停止スイッチ10の誤動作を防止し、信頼性を高めることが可能となる。しかも、非常停止ボタン40と復帰ボタン42との双方が、筐体12の前面側から操作可能な位置に設けられているため、列車非常停止スイッチ10がプラットホームの柱に埋め込まれて設置されても、双方のボタンを問題なく操作することができる。【選択図】図2
