The A3PBF1-600G-01 is a flush green momentary pushbutton with a single normally-closed (1NC) contact block. The "flush" actuator sits level with the bezel — no protruding button to catch a sleeve or tool, which matters on a crowded panel face where accidental actuation is a concern. The 1NC configuration means the contact is held closed in the rest state and opens only while the button is pressed, suited for circuits where a break in continuity initiates a stop or alarm.
Deployment context
Flush pushbuttons of this type mount into a standard 22 mm or 30 mm panel cutout — verify the specific diameter required for the A3PBF1-600G-01 before cutting. The green color and momentary action make it a natural fit for a start or reset function on a machine control station, but the 1NC contact means the circuit logic is inverted: the contact opens on press. That is typical for a stop or estop input where a broken wire or failed pushbutton fails safe to the open (stopped) state. The flush profile reduces the risk of unintended actuation in a high-traffic panel area.
