The 894901000 is a panel insert component for the E010 Series sealed momentary pushbutton switches, designed to accept an LED for indicator light assembly. This nylon panel insert features a 0.200 inch diameter hole that snaps securely into the switch frame, allowing integration of LED indicators for visual feedback in instrumentation, telecommunications, and computer peripheral applications. The insert is process-sealed to withstand soldering and cleaning, maintaining the switch's sealed integrity while providing a mounting point for standard LEDs. Available in white, black, and red finishes, the 894901000 panel insert enhances user interface functionality by combining momentary switch operation with visual status indication in compact panel-mounted designs.
