The A3PLE1-6L4W-11 is an illuminated pushbutton with a 2-position momentary action, extended operator, 120V AC lamp, white lens, and one normally-open plus one normally-closed contact block.
The 120V AC lamp voltage matches standard North American control-voltage panels; verify the lamp type (incandescent or LED) for your application's expected service life. The 2-position momentary action with extended operator suits flush-mount enclosures where the actuator needs to protrude past a panel overlay or gasket. One N.O. and one N.C. contact block provides a basic start/stop or enable/disable pair — adequate for a single-function pilot station but not for multi-contact interlocking.
