The A3PLE1-6L5M-11 is an illuminated pushbutton with a 2-position momentary action, a built-in 120V transformer, an amber lens, and one normally-open plus one normally-closed contact block. The integrated transformer powers the amber LED directly from the 120V line, so no separate power supply or dropping resistor is needed in the panel — just the two wires to the contact block and the line connection to the transformer primary.
Mounts in a standard 22.5 mm panel cutout. The 1NO+1NC contact block snaps onto the switch body; the transformer module clips behind the lamp housing. Wire the transformer primary to the 120V supply, the LED terminals to the transformer secondary, and the contact block to the PLC input or relay coil. Spring-cage terminals accept 0.5–2.5 mm² wire; strip length 8 mm.
