Selection Notes
Pick this variant for pulse commands such as Start or Reset, where the operator presses and releases and the LED gives status feedback: the 1 NO contact closes only while held, unlike the EMERGENCY STOP variant's latching 2 NC pair. Its 1,000,000-cycle rating fits a control that gets pressed often, and the 5 supplied lens colors let one part number cover several button colors on the same panel.
