MANUAL SWITCH OPERATION DISPLAY MECHANISM FOR RAILROAD SIGNAL SECURITY DEVICE

PROBLEM TO BE SOLVED: To realize a manual switch operation display mechanism for a railroad signal security device for confirming a switch handling state at a glance without using electric power.SOLUTION: Not only a manual switch mechanism 20 but also an operation display mechanism 30 are built in a casing forming a display window 12 on an operation surface 11. The manual switch mechanism 20 comprises a switch body part 23 for allowing a railroad signal security device to simulate train detection according to an operation state and a linear operation switch shaft 22 for allowing the switch body part 23 to switch the operation state according to the operation of an operation object part 21. The operation display mechanism 30 comprises a rocking member 32 for rocking in response to the operation of the linear operation switch shaft 22 for visually displaying the operation state of the switch body part 23, a fixed support shaft 31 for supporting this member in the rocking center and a display surface 33 that is in a part selectively coming to the inside of the display window 12 according to a rocking state of the rocking member 32 among a surface of the rocking member 32 and on which the display content is written.
