The 30-mm Mount illuminated emergency stop button combines status indication and safety. The e-stop provides an illuminated base that turns from yellow when the button is armed to flashing red when the button is pushed. This alerts operators visibly to which button was pressed, allowing users to fix the problem quickly and reset only the button that was activated. The base of an armed button also can turn to a steady red indication when a stop condition exists by applying an external signal. The buttons are available with two-color yellow and red lighting, red lighting or a non-illuminated black base.
