The A3PLE1-6LLW-91 is an illuminated push button from the Omron A3P series, configured as a 2-position momentary switch with an extended operator, a white LED for 6-24V supply, and a 1NO1NC contact block. It's the kind of panel-mount control you'd see on machine start/stop stations, conveyor jog panels, or any operator interface where a maintained-action button with status indication is needed.
The 6-24V white LED covers common control-voltage ranges — 6V for older DC panels, 12V and 24V for modern PLC I/O or relay logic. The 1NO1NC contact block gives one form-C set: normally-open for a start signal, normally-closed for a stop or interlock feedback. The 2-position momentary means the button returns when released, so it's suited for jog or pulse-triggered actions, not maintained on/off. The extended operator projects further from the panel face, making it easier to actuate with a gloved hand or in a recessed enclosure.
