PURPOSE: To provide an elevator shaft terminal switch allowing the defect of the contact thereof to be visually confirmed from an elevator hall or on a remote monitor panel. CONSTITUTION: Light emitting diodes 21 and 22 are connected to the contact of an elevator shaft terminal switch, and arranged at such a position as easily visible externally, thereby allowing the state of switch contact resistance to be visually confirmed. In this case, the diodes 21 and 22 for showing the state of switch contact resistance are laid in the switch, or a terminal switch central display panel fitted with the diodes 21 and 22 is laid on a control board or in a cage. In addition, an elevator remote control panel and remote monitor relay are provided to monitor the motion of an elevator. |
