The Eaton A3PLE1-6L2G-11 is a 2-position momentary illuminated pushbutton with an extended operator, green LED at 24 V, and one normally-open plus one normally-closed contact block. This is the kind of panel-mount switch you'd spec for a start/acknowledge station in a control cabinet where the operator needs visual confirmation that the circuit is live.
The 24 V green LED is the pilot light built into the actuator — it lights when the coil or circuit is energized, giving the operator a clear status indication without a separate indicator lamp. The 1NO+1NC contact arrangement covers both a make and a break signal from a single button press, which is typical for a start (NO) plus a feedback or interlock (NC) in a control circuit. The extended operator (EXTND) means the button protrudes further from the panel face than a flush operator — useful when the operator wears gloves or when the button needs to be reached through a thick enclosure door. The 2-position momentary action returns to rest as soon as pressure is released; there is no maintained or latching position.
Deployment context
This pushbutton mounts through a standard 22.5 mm panel cutout and connects to the contact block via the Eaton A22 series mounting system. In a wet well or washdown environment, the plastic operator and LED housing are rated for the enclosure IP rating you pair them with — the switch itself does not carry an IP rating in the evidence, so the panel builder must seal the cutout with a gasket or boot if the cabinet is NEMA 4X.
